Plaça de Gal·la Placídia is a square split between the districts of Gràcia and Sarrià-Sant Gervasi, in Barcelona, Catalonia, Spain.
The Mercat de la Llibertat, one of the district's 19th century markets, has been provisionally relocated in this square.
The Col·legi d'Economistes de Catalunya headquarters are currently under construction on the square, and due to open in 2010.
It's named ultimately after the Roman empress Galla Placidia and, also, after a Catalan Opera based on her life, written in 1913 by Jaume Pahissa.
[1] The square is the site of the Ferrocarrils de la Generalitat de Catalunya (FGC) station Gràcia, served by Barcelona Metro lines L6 and L7 and the remainder of Metro del Vallès services.
