The Leiden Loop is a walking route that includes 30 of the most notable tourist attractions in the Dutch city of Leiden. Among other things, walking the Leiden Loop will take you past the birthplace of the famous Dutch painter Rembrandt.
The local tourist information office (VVV) provides a map that shows the route and signs like the one in the picture above make it hard to make mistakes that cause you to deviate from the route.
There are signs like this all over the city.
This is one of several pictures that accompany a blog post I wrote about the Leiden Loop.
