The Orthodox church of St George in Paldiski is a typical example of sacral structures of its era - a stone church with classicist baroque roots, it was built between 1784 and 1787 and was consecrated at the end of that year. However, its history dates back even further: the Paldiski Apostolic Orthodox congregation is considered to have been founded in 1721, when a simple church was constructed here for the soldiers and workmen who had been sent to Paldiski to carry out fortifying work commissioned by Russian tsar Peter the Great. A wooden church replaced the original church (constructed from 1724-1728 to the designs of an architect named Moor) and was consecrated in late 1728 in honor of St George the Martyr.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
