Teatro Arriaga is an opera house in Bilbao. It was built in Neo-baroque style by architect Joaquín Rucoba in 1890, the same architect that built the city hall. It is named after Juan Crisóstomo de Arriaga, known in his time as the 'Spanish Mozart'. The theatre was rebuilt in 1985 after severe flooding destroyed it in August 1983.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
