About Peebles
Learn more about the host city, Peebles.
Peebles is a town in the Scottish Borders, with a population in 2020 of 9000. The name is Brythonic: pebyll meant "tents" or a temporary dwelling place. It's a market town and had a textile industry, which collapsed in the 1960s. It became a byword for provincial tranquility: to say that somewhere was "like Peebles on a Sunday" was not necessarily a compliment. It's nowadays a commuter town for Edinburgh. The main reason to visit is Traquair House, and to walk the nearby hills and forests.
