The Guggenheim Museum Bilbao is a museum of modern and contemporary art designed by Canadian-American architect Frank Gehry. The museum was inaugurated in 1997 by King Juan Carlos I of Spain, with an exhibition of 250 contemporary works of art. Built alongside the Nervion River, which runs through the city of Bilbao to the Cantabrian Sea, it is one of several museums belonging to the Solomon R. Guggenheim Foundation and features permanent and visiting exhibits of works by Spanish and international artists. It is one of the largest museums in Spain.
One of the most admired works of contemporary architecture, the building has been hailed as a 'signal moment in the architectural culture', because it represents 'one of those rare moments when critics, academics, and the general public were all completely united about something', according to architectural critic Paul Goldberger. The museum was the building most frequently named as one of the most important works completed since 1980 in the 2010 World Architecture Survey among architecture experts.
References:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
