Designed by the prominent Architect Frederick Clarke Withers, the chapel’s construction began in June 1888 and completed the following year. The exterior of the chapel, constructed in a number of materials, is richly textured and subtly polychromatic. The warm red brick of the walls, laid in a modified version of the Flemish bond, is enlivened by the random interspersing of gray brick. Smooth brownstone window and the door enframements, quoins, and ornamental detail contrast effectively with both the brick and rough-faced gray stone of the basement story. This gray stone, used for many of the institutional buildings on the island, is the gray gneiss granite quarried on the island since the 18th century.

The plan and massing of the chapel are simple and clear. Two projecting entrance porches, flanked by lampposts, lead to two ascending stairways within the deep narthex.

The scope of work included the removal of the non-original asphalt shingle roof and restoring the historic slate shingle with copper sheet metal flashings at the apse, narthex, and nave roofs; brownstone repairs, masonry repairs and steel window restoration. Once the exterior restoration project concluded and interior restoration project commenced focusing on the narthex pair of large wood double doors leading from the entry stair and the interior pair of wood double doors leading from the narthex to the chapel. Lighting upgrades followed with restoring the wood-paneled ceilings to the historic stained finish.
