Beykoz Mecidiye Pavilion
The Mecidiye Pavilion is the first modern style imperial stone structure that was built by the Bosphorus. It is older than the 19th century Ottoman palaces Dolmabahçe and Beylerbeyi. Following a six-year restoration, it was turned into a museum in 2016, after having been in public use,mostly as a hospital, for almost a century.
