Gashouder is one of the most beautiful marvels of the Amsterdam city. This building is made of iron and steel and is often used as a backdrop for several commercial shootings and movies. Gashouder was formerly the biggest gasometer in all of Europe. However, now the place is used as a party venue and is well known for a lot of hip parties that the venue hosts. If you are looking to explore the city and have some fun times, this is the place to go.
