for both—astronomy and navigation. It became a state institute in 1833. Similarly,
two domes are also characteristic in the design of the Astronomical Observatory of
the University of Warsaw, Poland (1825), by architects Chrystian Piotr Aigner
(1756–1841), Michał Kado (1765–1824), and Hilary Szpilkowski (1753–1827),
and for the old observatory in Brussels in Saint-Josse-ten-Noode (1826), initiated
by Adolphe Quetelet (1796–1874).
The standard architecture for observatories of the nineteenth century became the
Three-Dome-Facade since the 1830s, because of the increased number of instruments being used (refractors, heliometer, meridian circle or transit instrument).
After the great fire in Turku in 1827, the new observatory was designed by Carl
Ludwig Engel (1778–1840), a friend of Schinkel, in Helsingfors/Helsinki (1834),
on the Tähtitorninmäki Hill (Lehti & Makkanen, 2013). This was the earliest example of the Three-Dome-Facade with wooden cylindrical domes. The middle tower
had a time ball for navigational purposes as an addition. In 1890, a real rotating
dome was constructed for astrophotography.
The old observatory in Kazan, Tartastan, Russia, (Fig. 6), was constructed by the
architect Mikhail Petrovich Korinfsky (1788–1851) in Neoclassical style, in 1837.
This remarkable curved building has a meridian line and offers the additional possibility to observe not only in the meridian, but also in the prime vertical.
