The Municipal Stadium in Poznań sometimes called Bułgarska Street Stadium or INEA Stadion for sponsorship reasons, is an association football stadium in Poznań, Poland. It has a league capacity of 43,269 (all seated). The stadium was originally built between 1968 and 1980. From its inauguration in August 1980, Lech Poznań has used the ground as its main venue. Since 2010 it has also been used by Warta Poznań. The ground is situated on the street ul. Bułgarska in the southwestern part of the city (Grunwald district).
In the years 2003–2010, the stadium underwent a complete reconstruction, including the building of four new fully covered stands. Currently it is the fifth-largest stadium in Poland (after National Stadium, Silesia Stadium, The Municipal Stadium in Wroclaw and Stadion Energa Gdańsk) and third largest in Ekstraklasa (after the latter two). The grand opening after final renovation took place on 20 September 2010, with Sting's Symphonicity Tour concert.
