The Thon Estate, named after the German courtesan of King George I, was built by Ernst Ziller at the turn of the 19th century.At the time, the manor occupied an entire city block.

By the late 20th century the site had been reduced to a mere four acres, with the Church of Ag. Nikolaos being the only structure remaining from the original site.
