The Dom Tower of Utrecht is the tallest church tower in the Netherlands, at 112.32 metres 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.
