St. Casimir Church in Klaipeda features a striking modern architectural design characterized by strong vertical lines. The facade is defined by light concrete elements, narrow vertical glass panels, and a prominent bell tower topped with a metal cross. A smaller adjacent building with a matching roof structure stands nearby within the church complex.

The surrounding area is well-maintained, featuring green lawns, young trees, and a paved walkway leading toward the main entrance at the base of the tower. A low wire fence borders the site, and a white passenger car is visible parked on the road in the lower left corner.
