Grote of Sint-Laurenskerk is a Protestant church and only remnant of the medieval city of Rotterdam. The church was built between 1449 and 1525. In 1621 a wooden spire was added to the tower, designed by Hendrick de Keyser. Poor quality of its wood caused the spire to be demolished in 1645. A stone cube was added to the tower, which proved too heavy for the foundation in 1650. New piles were driven under the tower and in 1655 the tower stood straight again.
This church was the first all stone building in Rotterdam. Many important events took place here. The last priest of the Laurenkerk was Hubertus Duifhuis. The Reformation took place in 1572 and the Laurenskerk became a Protestant church. Ministers of the church include Laurens Johannes Jacobus van Oosterzee, Abraham Hellenbroek, Jan Scharp and J.R. Callenbach, who wrote a book about the history of the church a few years before the Rotterdam Blitz. The church is still used for worship of the Protestant Church.
In the Rotterdam Blitz on May 14, 1940 the Laurenskerk was heavily damaged. At first there were calls to demolish the church, but that was stopped by the Germans. The provisional National Monuments Commission had both supporters and opponents of restoration. In particular, committee member and architect J.J.P. Oud opposed rebuilding in 1950 and presented an alternative plan which would preserve only the tower. Next to the memorial a new, smaller church would be built. This alternative plan was rejected, particularly because restoration of the Laurenskerk was viewed as a symbol of the resilience of Rotterdam's community. In 1952, Queen Juliana of the Netherlands laid the foundation stone for the restoration, which was completed in 1968.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.
