The chapel was made after the Catholic Emancipation Act in 1829, which allowed Catholics to worship openly again. Previously the room was a billiard room and it is situated immediately over the Brew House. This is quite obvious when brewing is taking place! The white marble altar was brought over from Italy by Henry Maxwell Stuart and is the work of the Italian sculptor Brumidi. The carved oak panels on the walls are scenes from the life of Christ. They are Flemish and were brought to Scotland by Scottish craftsmen who travelled through the Low Countries in the early part of the 1500’s. In former times the family sat behind the curtains at the back of the chapel where there was a fire. This area has now been made into a sacristy.
