Vartiovuori observatory is the former observatory of the Royal Academy of Turku. Building was completed 1819 and it was designed by German architect Carl Ludvig Engel. By its style, the neoclassical observatory is typical work of Engel and it has obvious similarities to Helsinki University Observatory and Pulkovo Observatory (in St. Petersburg, Russia) designed also by him. Building is located on top of the Vartiovuori hill, close to the cathedral and Aura river and it's well visible from many places in city center.
The Academy moved to Helsinki after the Fire and got a new observatory there few years later. Instruments were moved to Helsinki and finally Vartiovuori Observatory became defunct 1834. At 1836 Åbo Navigationsskola (Maritime School) moved into empty observatory building and stayed there until 1967. Between 1986 and 1998 building was a maritime museum and during the repair of the Turku Art Museum 1999–2005, the changing exhibitions were placed in observatory. Currently and also in the picture, a flag of the foundation Stiftelsen för Åbo Akademi flies over the building.
The observatory and several wooden houses (current Luostarinmäki Handicrafts Museum) on the hill were saved from the Great Fire of Turku 1827.
References:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
