St. George's Church in Drohobych is one of the oldest and best preserved timber churches of Galicia. The church is a monument of Galician wooden architecture of the late 15th - early 16th centuries, one of the best preserved and one of the best monuments of ancient Ukrainian sacral architecture. Built in the 15th century, it has been rebuilt several times and given the final architectural forms by the talented Ukrainian architect Hryhoriy Tesla from Drohobych. The church is part of the wooden architecture department of the Museum of Drohobych region.
The church consists of three parts. The central block is square in plan and comprises the nave. Two other blocks contain the double apse and the narthex. Between 1678 and 1711, the church was renovated: the interior was frescoed, the octagonal structures built up, and a new belfry appeared.
It is one of the 16 churches that comprise a World Heritage Site named the Wooden tserkvas of the Carpathian region in Poland and Ukraine.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.
