The Op Solder Museum added a modern wing in 2015 in the adjacent building which is connected to the original house by an underground passageway.

Without doubt, the centrepiece and highlight of the museum is the beautiful small church spanning the attics of 3 adjacent houses. The church can seat up to 150 worshippers and has magnificent decor with its own organ.

Public Catholic services were officially forbidden from the late 16th century after the Protestants took power in 1578. The Op Solder church dates back to 1663 having been built by wealthy Catholic merchant Jan Hartman (1619-1668) who lived in the house with his family.

The city authorities under the influence of William of Orange turned a blind eye to such private places of worship.

The church continued in use up until 1887 and the following year the house was turned into a museum – it is in fact the second oldest museum in Amsterdam after the Rijksmuseum.

The old house contains a number of restored rooms with various religious artefacts, paintings and some period furniture including a 17th century kitchen, typical sleeping quarters and a small confessional room.

Also on display is a large amount of ceramic ware – these were discovered during the last museum renovation. They originate from the cesspit of the house where old pottery was discarded.

The modern wing and underground passage provide additional exhibition space with multimedia presentations.

A visit to the museum takes about 1 hour. Be mindful that the house contains some steep staircases so you will need to have a degree of mobility to reach all areas.

There is an introductory film on show in the basement before entering the old house. Alongside is a large scale model of the house.

The included audio tour (8 languages available – Dutch, English, French, German, Spanish, Italian, Chinese and Russian) gives further context and insight at points of interest around the house and church.

The Op Solder Museum is a fascinating place to visit combining elements of a 17th century merchant house, a beautiful hidden church and the underlying themes of tolerance and freedom of worship. It is a peaceful haven from the surrounding red-light district and worth a visit.
