Cathedral of Saint Martin, Utrecht

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.

The building is the one church in the Netherlands that closely resembles the style of classic Gothic architecture as developed in France. All other Gothic churches in the Netherlands belong to one of the many regional variants. Unlike most of its French predecessors, the building has only one tower, the 112-metre-high (367 ft) Dom Tower, which is the hallmark of the city.

The first chapel in Utrecht was founded around 630 by Frankish clergy under the patronage of the Merovingian kings but was destroyed during an attack of the Frisians on Utrecht shortly thereafter. The site of this first chapel within Utrecht is unknown. Saint Willibrord (died 739), the Apostle to the Frisians, established a second chapel devoted to Saint Martin on (or close to) the site of the current building. This church was destroyed by the Normans in the 9th century during one of their many raids on Utrecht, but was reconstructed by Bishop Balderic in the 10th century. During this period St. Martin's came to be the principal church of Utrecht, see of the bishop. The church had its own small territorial close (known as an "immunity") and was led by a cathedral chapter of canons, who generally belonged to the nobility.
