query: What is the oldest building in Oslo?

Old Aker Church (Norwegian: Gamle Aker kirke) is a medieval era church located in Oslo, Norway. An active parish, the church is the oldest existing building in Oslo.[1] The church is surrounded by Old Aker Cemetery.
passage: Barcode Project
The project "is among the most protested . . . ever in Oslo." A petition campaign in opposition to the building of the high-rises received over 30,000 signatures in 2007, and according to a survey by "Aftenposten" in December of the same year, 71% of the population of Oslo opposed the project. In 2008 a charrette was organized to find alternatives.
During work on the Barcode project, the remains of at least nine wrecked ships were uncovered, up to 18 m long and provisionally dated to the first half of the 16th century. This is the largest collection of historical shipwrecks found in Norway. The Barcode site, like the rest of the Bjørvika neighborhood, was underwater until the mid-19th century. Approximately 1,100 clay pipes, Chinese porcelain, and other artefacts were also found. The Norwegian Maritime Museum has a selection on exhibit.
