Set in Amsterdam's Red Light District, the Church of Our Lord in the Attic is one of the oldest museums in the city. Focussing predominantly on the Catholic faith, history and architecture, the Church of Our Lord in the Attic is a true spectacle of the glorious Dutch Golden Age. Built in the 17th century, the Church of Our Lord in the Attic was actually a house whose top floor was converted into a church. Bought by Jan Hartman around 350 years ago, the attics of the building at Oudezijds Voorburgwal and the two adjacent buildings on Heintje Hoekssteeg were built into a grand Catholic church. The church was named Church of Our Lord in the Attic in the 19th century and served this parish till 1888.
