The Sint Janskerk (St. John's Church) is a large Gothic church, known especially for its stained glass windows, for which it has been placed on the UNESCO list of Dutch monuments.
The church is dedicated to John the Baptist, the patron saint of Gouda, and was built during the 15th and 16th centuries. In 1552 a large part of the church burned, including the archives. Most information of the early period is taken from the diaries of Ignatius Walvis. Around 1350 a tower was built (only the lower part remains). In 1485 the foundation was built for the present-day choir. This expansion made the church the longest in the Netherlands, with a length of 123 meters.
The stained glass windows were made and installed primarily by the brothers Dirk and Wouter Crabeth I, in the years 1555-1571, and after a short stop for the Protestant Reformation, until 1603. During the Reformation the church was spared, because the city fathers sided with the reigning king Philip II of Spain, rather than William the Silent, representing the Orange rebels. Later, after the orangists conquered the northern half of Holland, Gouda reverted to Orange in 1572. It was only during this period that the church was in danger, and three weeks later an angry mob stormed the church and plundered the contents, but fortunately left the windows intact. The church was closed, but many wealthy regents of the city attempted to have it reopened. In 1573 the Gouda council prohibited the practise of Roman Catholic religion and in the summer it was opened for the Protestant Dutch Reformed faith, which it still has today.
In 1934 the Van der Vorm chapel was added to house the 7 regulierenglazen from the monastery in the town of Stein in Limburg.
In 1939 the stained glass was removed in anticipation of war with Germany. Later during the war, in 1944, when 51,000 men were called for service from Schiedam and Rotterdam, about 2800 were marched to Gouda, where they spent the night in this church on November 10.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
