The Church of St Nicholas is a Greek Catholic church in Valletta. It was originally built to serve as a Greek Orthodox church in 1569. Following the Union of Brest in 1595-96 the Greek Catholic Church came into existence. It was in 1639 that the then parish priest decided to separate from the Orthodox church and join the Greek Catholic Church.
Some time later it was decided to rebuild the church to the design of the Italian architect Francesco Buonamici. The church was rebuilt on the ground plan of a Greek cross in 1652. It has a dome over the crossing supported by four free-standing columns, and a choir in the apse. On September 17, 1766, the parish church and the Confraternity of the Holy Souls signed a concordat that regulates their relations.
The church suffered considerable damage during World War II; it was repaired by the year 1951.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.
