When we visited Viljandi on March 26, 2011, I finally got some decent pictures of a church. This is St. John's Lutheran, built in the 1500s. The steeple dates to 1815.
During Soviet times, the congregation was thrown out and the church was used to store furniture. Luckily, the church wasn't destroyed (I have lots of pictures of the ruins of churches in ruins thanks to the Soviet occupation), and the church was re-consecrated in 1992.
And it was on my way to this church that I made my first ice-related backside plant in Estonia. Cobblestones are hard!
