During Christmas break I visited Teylers museum in Haarlem. It is the oldest museum in the Netherlands and was founded in the 18th century. I went there many years ago but I was very young and didn't remember too much about it. When I was very excited after visiting the Ethnographical museum in Stockholm my mom suggested that I might like to visit Teylers again.
At Teylers museum they have some paintings, old coins and a temporary exhibition, but what I like most about it is their collection of natural history items and old science equipment.
