Tallinn's Old Town is listed as a UNESCO World Heritage Site.  It is divided into a "lower town" and Toompea hill.

Greater Coat of Arms of Tallinn

This great card came from Patrik (March05, 2014) Direct Swap Postcrossing. It shows the old town of Tallinn.  In the lower panel, the steeples of St. Nicholas' church (Niguliste kirik) and St. Olaf’s Church (Oleviste kirik) soar above the houses around.
I also like the stamp depicting the flag of Estonia.
