Coat of Arms and History
The castle was first documented in1234; soon afterwards the town is emerged below it. It was promoted as the town in about 1308 – 1352. Loket already used its seal with a bent arm in elbow before the Hussite movement as canting arms. Such armed arm with the sword probably on a red background became an emblem of the town. The emblem was improved with other rights and privilege from 27th May 1561; the old emblem remained in the upper part of the shield while lower part was refilled with a common town wall and a gate. Coat of arms was given with a lion as a shield – bearer.
The flag has come from recent time; town was entitled to use it by Václav Klaus – the chairman of the Chamber of Deputies of the Czech Republic on 16th February 1999.
The sheet is created with two horizontal stripes; red and white stripes in a ratio 2:1.
In the upper stripe facing a flagpole there is white bent armed arm with gauntlet wielding sword oriented to the streaming tip. The ratio width to length is 2:3.
