Page "Anne de Mowbray, 8th Countess of Norfolk" Paragraph 5

Anne was entombed in a lead coffin in the Chapel of St. Erasmus of Formiae in Westminster Abbey.

When that chapel was demolished in about 1502 to make way for the Henry VII Lady Chapel, Anne's coffin was moved to a vault under the Abbey of the Minoresses, run by nuns of the Order of Poor Ladies.

Her coffin eventually disappeared.
