To see 17th-century Art for Free you just must vistit Civic Guards’ Gallery. Just inside the Kalverstraat gate to the Amsterdam Historical Museum is a glass-roofed walkway that houses impressive 17th-century portraits, on display to the public at no charge.
The subjects of the 15 huge paintings are the Amsterdam Civic Guards that served in the 1600s. The most famous Civic Guard portrait is, of course, The Night Watch in the Rijksmuseum; these paintings have a similar but more formal feel than Rembrandt’s masterpiece.
