Holy Trinity Greek Orthodox Church, Vienna

Since 1963 the cathedral has been the seat of the Greek Orthodox Metropolis of Austria (the Ecumenical Patriarchate of Constantinople: the Metropolis of Austria and Exarchate of Hungary and Middle Europe).

Greek Orthodox churches have existed near this site since 1787, as a result of the 1781 Patent of Toleration issued by Joseph II, Holy Roman Emperor.

Greek-Austrian diplomat and philanthropist Simon Sinas funded the project,[1] one of many collaborations with Hansen in Vienna and Athens.

The exterior features two-tone brickwork and gilded archways.

[2] The elaborately ornamented sanctuary shows a stylish allusion to Baroque church architecture typical of southern Germany and Austria.
