Almost every underground station in Amsterdam has a fascinating story behind it. My favourite one is metro station ‘Weesperplein,’ because it has a hidden station underneath the actual station that was meant for the 'Singellijn.' However, that line was never build and the second station remained useless. Besides that the hidden station was also equipped to serve as a shelter during the cold war. The large doors that were meant to hermetically close the building are still visible at both ends of the platform. Other small details, like the panels in the ceiling than can be used as tables when turned around, are also silent references to the building’s former use.
OT301 is a cultural centre in the former building of the Film Academy at the Overtoom. It’s a good place to get drunk, watch a movie or to eat. It's not too expensive, like most other places in Amsterdam, and the ambience is good.
This is the area where I always make my round if I want to see some good works in the galleries. It’s a nice neighbourhood with many galleries in a walking distance from each other.
