Within close distance from Syntagma Square, at Filellinon Street, across the National Garden stands one of the most impressive Byzantine churches in Athens, Sotira of Lykodimos.It is a building of the 11^th century, which suffered repeated disasters and was restored in the 1850's with donations by the tsars Nikolaos I and Alexander II.The church has been dedicated to the Holy Trinity since then and has been bestowed to the Russian community of Athens and therefore it is also known as the Russian Church.The iconographies in its interior are works of the Bavarian painter L. Thiersch.
