ESTONIA
I visited Estonia in August of 2021

Patarei initially served as an army barracks - although from the outset it was a damp, uncomfortable place to be stationed. It was first used as a prison in 1920 following Estonian independence, but it gained its notoriety during the Soviet and German occupation. Numerous people were brutally interrogated and executed here, including 250 French Jews killed by the Nazis who are remembered by a simple memorial stone near the southern entrance.*

Only the massively high Gothic stone walls remain of this convent, which was completed in 1436. The rest was destroyed courtesy of Ivan the Terrible during the Livonian War in 1577.*
