St. Martin's Cathedral, Utrecht, or Dom Church (Dutch: Domkerk), is a Gothic church dedicated to Saint Martin of Tours, which was the cathedral of the Diocese of Utrecht during the Middle Ages. It is the country's only pre-Reformation cathedral, but has been a Protestant church since 1580.
It was once the Netherlands' largest church, but the nave collapsed in a storm in 1674 and has never been rebuilt, leaving the tower isolated from the east end.
Religion in the Netherlands was dominated by Christianity between the 10th and 20th centuries. In the late 19th century, roughly 60% of the population was Calvinist and 35% was Catholic. Also, until The Holocaust, there was a noticeable Jewish minority. Since World War II, there has been a significant decline in Catholic and especially Protestant Christianity, with Protestantism declining to such a degree that Catholicism became the foremost form of the Christian religion. The majority of the Dutch population is secular; however, historic societal pillarisation (verzuiling) based on religious lines continue to influence parts of Dutch society. Relatively sizable Muslim and Hindu minorities also exist.
The Dom Tower (Dutch: Domtoren 'Cathedral Tower') of Utrecht is the tallest church tower in the Netherlands, at 112.32 metres (368.5 feet) in height. It is considered the symbol of Utrecht. The tower was part of St. Martin's Cathedral, also known as the Dom Church, and was built between 1321 and 1382, to a design by John of Hainaut. The cathedral was never fully completed due to lack of money. Since the unfinished nave collapsed in 1674, the Dom tower has been a freestanding tower. The tower stands at the spot where the city of Utrecht originated almost 2,000 years ago.
