North of the Municipal Museum in Helsinki, on the shores of Töölö Bay (Töölönlahti), is the Finlandia Hall, a concert and convention hall designed by Alvar Aalto and built-in 1971 with a white facade of Carrara marble. The marble is also used on the inside of the structure. Details appear in hardwoods and ceramics.
The main concert auditorium is a stunning site and is famous for its acoustics. Another standout feature is the wide Venetian staircase that leads from the ground floor to both the main auditorium and chamber music hall. The Final Act of the Conference on Security and Cooperation in Europe was signed here in July 1975.
To the north of the hall is an excellent park (home to large chess boards and chess pieces), and beyond this again is the new Finnish National Opera House, inaugurated in November 1993 with a performance of the opera “Kullervo” by the Finnish composer Aulis Sallinen.
