"Utrecht city and municipality is the capital and most populous city of the Dutch province of Utrecht. It is located in the eastern end of the Randstad, and is the fourth largest city of the Netherlands.
The Dom Tower of Utrecht is the tallest church tower in the Netherlands, at 112.5 metres (368 feet) in height,and the Gothic-style tower is the symbol of the city. The tower was part of the Cathdreal of Saint Martin, also known as 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 became a free standing tower." - in: wikipedia
