This is a very pleasant, well-done museum. According to its web site, http://www.evm.ee/keel/eng/
"The Estonian Open Air Museum is akin to a village, with 12 farms, as well as its own church, tavern and schoolhouse. There are a number of mills, a fire station, fishing net sheds as well as a dancing area and a village swing.
The museum is located in a lovely, well-maintained forest park on a high sandstone bank on Kopli Bay, just 15 minutes drive from the center of Tallinn."
