Today was Open Monumentendag in the Netherlands, which means that many monuments, otherwise closed to the public, are open for free exploration. We had a walk around our town Leiden today and came across some really nice 1940’s Escher intarsia (a form of wood inlaying) works at the city’s Town Hall.
M. C. Escher (1898–1972) was a Dutch graphic artist known for his often mathematically inspired drawings of impossible constructions and infinite patterns.
We saw four of the beautiful works: two square works with infinite fish, a clock with birds, and a huge 1940 map (at least two meters across) of the city of Leiden. The map (which even showed the street that our house is on!) contains several planned neighborhoods that were never built. The map shows a canal to the north of the city along a planned industrial area, but the canal was never dug.
