In which country is the world's oldest parliament?

The Alþingi is the national parliament of Iceland. It is the oldest surviving parliament in the world[, a claim shared by Tynwald. The Althing was founded in 930 at Þingvellir. Even after Iceland's union with Norway in 1262, the Althing still held its sessions until 1800, when it was discontinued for 45 years. It was restored in 1844 and moved to Reykjavík, where it has resided ever since.
