The Munttoren, a tower in Amsterdam, the Netherlands, as seen from the river Amstel at dusk. The tower was originally part of the Regulierspoort, one of the main gates in Amsterdam's medieval city wall, dating to 1487. After a fire destroyed the gate in 1618, the tower was rebuilt in the Amsterdam Renaissance style, with an eight-sided top half and open spire designed by Hendrick de Keyser, featuring a clock with four faces and a carillon of bells. The name ("Mint Tower") refers to the time when it was temporarily used to mint coins in the Rampjaar ("disastrous year") of 1672 when both England and France declared war on the Dutch Republic, and silver and gold could not be safely transported to Dordrecht and Enkhuizen, where coins were normally minted.Photo: Massimo Catarinella
