In the heart of Kuching stands St. Thomas' Cathedral—a majestic Anglican church that has become one of the primary spiritual and architectural symbols of Malaysia. The modern brick building, erected in the mid-1950s, replaced an older wooden church, preserving the spirit of Sarawak's colonial past within its walls.

The main architectural highlight of the cathedral is its unusual bright red barrel-vaulted ceiling, which is a rare feature in classical Anglican architecture. The interior is impressive in its monumentality: the vaults are supported by 12 snow-white columns with arches reaching nearly 15 meters in height, creating a sense of space and light.
The wooden cross on the altar wall deserves special attention. The image of the crucified Christ on it was created with the cultural characteristics of the region in mind—the Savior's face is endowed with features characteristic of the indigenous population of Sarawak, emphasizing the inclusiveness and deep roots of the Christian mission in these lands.
