Leuk

Leuk (French Loèche) is a municipality of Switzerland and is the capital city of the district of Leuk in the canton of Valais in Switzerland.

Since it controls access to the Gemmipass, it had some importance from the time of Roman Raetia. The Leukerbad hot baths are just North of Leuk, towards the pass.

Loèche houses the installations of Onyx, the Swiss interception system for electronic intelligence gathering.

On 1 January 2013 the former municipality of Erschmatt merged into the municipality of Leuk.
