The Van Gogh Museum in Amsterdam will move from its present location on September 29th for some months. The museum will in this period be open, but at another address. The new address on which you can find the Van Gogh Museum until April 25th in 2013 is:
Van Gogh Museum
c/o Hermitage Amsterdam
Amstel 51, Amsterdam
T +31 (0)20 570 52 00
If you want to get to the museum using the public transportation in Amsterdam, for example the metro, then the nearest metrostation is Waterlooplein. The new location is also very close to one of the famous attractions of Amsterdam, the Magere Brug.
