The Trakai Kenesa is the Karaim prayer house on Karaimu Street, one of the few surviving Kenesas in Lithuania. The Karaim, a Turkic people practicing a form of Judaism, were brought to Trakai by Grand Duke Vytautas in the late 14th century as elite guards — known for their military skills, their distinct culture, and their absolute loyalty to their patron.
The wooden kenesa dates from the 18th century and has been carefully preserved. It is distinct in style from both Christian churches and mainstream synagogues — the prayer hall is oriented toward Jerusalem, and the architectural style reflects the Crimean origins of the community. Services are still held here on significant occasions. The surrounding area of Karaimu Street, with its wooden houses painted in three colours (one per window per tradition), preserves the Karaim neighborhood character.
