The Greek Orthodox Cathedral of St. Luke the Evangelist is the spiritual and community centre for Greeks from mainland Greece and Cyprus. It is one of three Orthodox Churches and the only Orthodox Cathedral in Scotland. It also serves all other Orthodox communities in Glasgow, such as Serbs, Romanians, Russians etc. The cathedral welcomes visitors of all denominations throughout the year, the traditional Easter service being a particularly well attended event, whilst the cathedral's participation in Glasgow's annual Doors Open Day provides visitors with another opportunity to visit this historic building.
