Serdika II

Serdika II Metro Station is an M2 line station of Sofia Metro. It was put into operation on August 31, 2012 and the station became transfer station between the Red and Blue lines together with Serdika, however it is not a true transfer station, but a tunnel-connection transfer station. Bulgaria's PM Boyko Borisov and the President of the European Commission Jose Manuel Barroso inaugurated the new section of the Sofia Metro, which was funded with EU money. The initial project name of the Metro Station was Sveta Nedelya Square, but this was changed by the city council shortly before the opening of M2 line.
