[1] Building of the chapel commenced in 1869,[2] soon after the estate was inherited by Hugh Grosvenor, the 3rd Marquess of Westminster, in conjunction with a major rebuilding of the hall.

[1] Above these is the clock stage, corbelled out from the shaft of the tower and surmounted by pinnacles at each corner.

[1] The narthex at the east end has a groin vaulted oak roof, and is paved with black marble and with encaustic tiles.

A continuation of this screen leads to the pulpit: this is also constructed in alabaster with Devonshire marble columns.

In the chancel is a recumbent effigy in alabaster of Constance, 1st Duchess of Westminster, by Joseph Boehm.

For the effigy, Boehm worked from plaster casts of the face and hands taken after her death.

The clock tower contains a carillon of 28 bells which were cast by Chavalier Severian Van Aerschodt of Louvain; it plays 31 tunes.
