St. Erasmus Chapel in Chester Cathedral

The high altar of Chester Cathedral contains a mosaic of the Last Supper by Salviati from 1876. Around 1870 during the restoration by G.G. Scott, the south aisle of the cathedral was shortened and its east end was converted into the St. Erasmus Chapel.

Designed by Clayton and Bell, the Salviati mosaics in the chapel from 1879 are dedicated to the memory of railroad contractor Thomas Brassey (1805-70) and his wife Maria Farringdon Harrison (d. 1877) by their sons Thomas, Henry Arthur (Harry) and Albert Brassey. Thomas the younger had built the Brassey Institute in Hastings.
