Vaalserberg
The Vaalserberg ("Mount of Vaals") is a hill with a height of 322.7 metres (1,059 ft) above NAP and the highest point in mainland Netherlands. The Vaalserberg is located in the province of Limburg, at the south-easternmost edge of the country in the municipality of Vaals, near the eponymous town, some three kilometres west of Aachen.
Before 10 October 2010, the Vaalserberg was the highest point in the Netherlands, until upon the dissolution of the Netherlands Antilles when Mount Scenery on Saba (the highest point in the Kingdom of the Netherlands) became part of the Netherlands.
