Founded in 1889, the Dr. Karl Remeis Observatory was built on one of Bamberg’s seven hills, the Stephansberg, at an altitude of 288m on the border of the town. The architect of this nice ensemble in historistic style was Georg Hofbauer of Bamberg according to plans by the architect Max Ißleiber, successor and employee of Hermann Eggen (1844--1920), who had already built the "German model observatory" in Strasbourg. The ceremonial opening of the Remeis Observatory took place on 24 October 1889.
The main building, a typical villa of the Wilhelminian period, built as a brick building with sandstone frames, had offices, the library and the custos’s flat on the ground floor. In the basement were the workshop and laboratory, on the first floor the director’s apartment (until 1978), the assistant’s flat on the second floor, and on the roof a platform for meteorological observations.

A covered corridor provides the connection to the unheated observation building. Two towers (12m high with a dome of 6m diameter) are arranged in east-west direction with a meridian hall between them. The iron construction covered with corrugated metal leads to a rapid temperature equalisation due to its good thermal conductivity. The instruments in the tower are based on strong fundaments - without any vibrations, which was also realised in Strasbourg, but this was by no means a standard at that time.
Foundation of a research observatory
The funds of 400,000 Mark came from the Bamberg lawyer (PhD, University of Erlangen, faculty of law, 1863) and amateur astronomer Dr. Karl Remeis (1837--1882), who left his fortune for the construction of the observatory, because he had no heirs. Remeis had erected a private observatory in his villa on Michelsberg. In 1879, he replaced his 3-inch telescope (7.2cm, f = 80cm), made by Fraunhofer of Munich with a 4-inch refractor (10.8cm, f= 1.4m) from Reinfelder & Hertel of Munich. In addition, he owned a 3-inch comet finder (7.8cm) by Merz of Munich, two universal instruments from Ertel of Munich and August Becker of Göttingen, and various smaller instruments. Finally, in 1881, he succeeded in acquiring a large 10-inch refractor (26.4cm, f = 3.9m, 1:14, wooden tube) from Dr. Hugo Schröder of Oberursel.
Remeis’ will of September 24, 1879, provided a total of 400,000 Mark: 180,000 Mark for the construction of the observatory, 70,000 Mark for the instrumentation, 80,000 Mark capital, from the interest the astronomer has to be paid -- this amount was underestimated, as it turned out later. Even though the foundation was not met with enthusiasm by the citizens of Bamberg and the magistrate, it was accepted in 1883.

Thanks to the generous endowment of an observatory, the name Remeis has survived to this day:
"The main part of my fortune should be used to set up an observatory in Bamberg. I am convinced that the best use of material goods is to support and promote scientific research, which elevates and ennobles people spiritually ... Astronomy ... is the science which helps man to an appropriate sense of self and his position in the universe, and at the same time enables him to find the eternal laws of the cosmos, to reflect on the idea of creation, and to feel a divine spark."
("Mein Vemögen soll seinem Hauptbestandteile nach zur Errichtung einer Sternwarte in Bamberg verwendet werden. Ich bin überzeugt, dass die beste Verwendung der materiellen Güter darin besteht, die wissenschaftliche Forschung, welche den Menschen geistig erhebt und veredelt, zu unterstützen und zu fördem .... Die Astronomie ... ist die Wissenschaft, welche dem Menschen zur richtigen Erkenntnis seiner selbst und seiner Stellung im Universum verhilft und zugleich aber auch ihn in die Lage versetzt, die ewigen Gesetze des Alls zu finden, dem Schöpfungsgedanken nachzudenken und in sich selbst einen göttlichen Funken zu fühlen.")
An observatory that goes back to a foundation was something unique in Germany, in contrast to the USA: there was only one state observatory (Naval Observatory, Washington, D.C.), all other large observatories were financed by foundations.
Fig. 4. Layout of Remeis Observatory (1889), 1:600 (Image courtesy: Remeis observatory)
The modern layout of Remeis Observatory was inspired by Strasbourg Observatory: The living quarters and offices are strictly separated from the observation buildings, the two domes and the meridian circle building -- laid out in west-east direction. The buildings are connected by a covered corridor.
After visiting 40 observatories, the first director Ernst Hartwig (1851--1923) planned the instrumentation of the Remeis Observatory. The main instrument was initially a heliometer -- the largest in the northern hemisphere -- in the Eastern dome, since 1946 it was replaced by a 60-cm-reflecting telescope. The Meridian Hall did not get a meridian circle for lack of money, but only a 3-inch transit instrument. In the Western dome was the 26-cm-Schröder refractor of Remeis, replaced by a Schmidt telescope.
From classical astronomy to modern astrophysics
At the end of the 19th century, the observation buildings were strictly separated from the office and residential buildings. This separation of functions only partially succeeded in the Strasbourg Observatory (1874), then in a mature form with the Observatorio de La Plata (1883/86), Argentina, and with the Nice Observatory (1888) -- the astronomy park was invented. The Bamberg (1889) and Hamburg observatories (1906--1912) as well as the American observatories on Mt. Wilson and Mt. Palomar also followed this modern idea of the layout of an observatory.
At the same time the emphasis of research is changing "From classical astronomy to modern astrophysics": This is associated with a change of the instrumentation: from meridian circle, refractor (equatorial), heliometer, comet finder to new astrophysical instruments such as astrographs, portrait lenses, reflecting telescopes, Schmidt telescopes, and various astrophysical laboratory instruments. Astrographs are instruments for determining star positions, i.e. for classic astronomical tasks, carried out using modern photographic methods. There are coordinate and spectra measuring devices as well as blink comparators for analysing the photographic plates.
The main activities of Remeis Observatory were not in classical astronomy but especially in the field of astrophysics. For more than 70 years, the observation of variable stars and the systematic sky survey of the northern hemisphere, in cooperation with the observatories in Babelsberg and Sonneberg, was the emphasis of research.

Already the first director Ernst Hartwig started with variable stars in 1891; they have been systematically examined for periods and type classification of the light curves, initially mainly variable stars of Algol type, but since 1897 also ß Lyrae type, and irregular variable stars like SS Cygni (today it is regarded as a cataclysmic variable -- a Close Binary System with the a red dwarf-type star, cooler than the Sun, and a white dwarf). From 1907 onwards, annual catalogues of positions and special features were published by the Remeis Observatory, which initiated a lively international exchange of observatory publications.
The interest in Variable Stars and Binaries continued also under Ernst Zinner. Together with Paul Guthnick of Potsdam-Babelsberg and Cuno Hoffmeister of Sonneberg, Zinner started a sky survey of the northern hemisphere in 1926 (until 1939). The sky was devided in 30 degree zones and photographed with identical Ernostar cameras (aperture 13.5cm, focal length 24cm) and 16x16cm photographic plates -- 6500 plates.
In Bamberg, also some smaller cameras were used: Tessar (aperture 3cm, focal length 14cm), 1931 to 1953, Tessar (aperture 9cm), 1953 to 1963, Dogmar (aperture 11cm, f=40cm), 1950 to 1963 -- 4500 plates.
But Zinner had never enough money to update the instrumentation of the observatory. In addition, he introduced the history of astronomy as a new field of research and got international recognition.

In 1959, 1962, 1965 and 1977, Wolfgang Strohmeier organized IAU variable star colloquia, which introduced the institute to international research.
He started a sky patrol of the southern hemisphere (sponsored by the German Research Organisation / Deutsche Forschungsgemeinschaft, DFG) with Aero Ektar cameras (aperture 10cm, focal length 61cm) in out stations in Boyden/South Africa (1963 to 1972, 10 cameras), San Miguel Observatory, Argentina (1969 to 1972, 6 cameras) and Mount John/New Zealand (1967 to 1976, 4 cameras) -- around 22.000 plates.

The result of the northern and southern sky patrol are 40,000 photographic plates, 1926--1939 and 1962--1976, which are archived in the old custos and workshop bulding. Sponsored by the DFG, in 2012 started a digitization research project of the plates, the APPLAUSE database and the integration into the international "Virtual Observatory".

History
Hartwig started astrophysical research: he acquired a stellar spectroscope, made by Toepfer of Potsdam. In 1894, Hartwig bought a wedge photometer, made by Toepfer of Potsdam, and a Zöllner photometer (1895), which was improved several times by Toepfer until 1907.

The building of Dr. Karl-Remeis Observatory, founded in 1889, is well restored. Only the meridian hall was later converted to a library, which has countless international journals, historically valuable publications from 263 observatories worldwide; in the upper floor were offices and flats for observers and students.

The Remeis Observatory is a good example for an astronomy park with separated buildings in a parc, the villa and the - unheated - observation buildings.
Other examples are: Nice (1886), Strasbourg (not a real parc, one dome is still on the main building), La Plata, Argentina (1883), Uccle Observatory Brussels (1891), Heidelberg-Königstuhl (1898), EAO Kazan (1901), and Hamburg-Bergedorf (1906--1912) - the best example of this kind, it follows very strictly this park layout.

The Remeis observatory was originally a public-local foundation and was only attached to the University of Erlangen-Nuremberg as an astronomical institute in 1962.
Astronomical relevance today
Research at Remeis-Observatory is done in three areas:
- Multiwavelength Astronomy,
- Stellar Astronomy, and
- X-ray Astronomy.
Since 2007 Remeis observatory has been part of the Erlangen Center for Astroparticle Physics (ECAP), in which the university has merged the research in the fields of neutrino physics, X-ray astronomy and space- and ground based gamma-ray astronomy.
