The Washington Window in Selby Abbey, in the British market town of Selby, contains a variant of the Washington coat of arms in the original 14th century stained glass. It is thought to be a benefaction to the abbey to commemorate John Wessington, Prior of Durham (1416–1446).
The Washington coat of arms can also be seen at the huge parish church in Garsdon, near Malmesbury, Wiltshire, where a branch of the family moved in Tudor times. A Washington memorial accompanies it.[1]
The design is often said to have inspired the Stars and Stripes and is used today as the coat of arms and flag of the District of Columbia.
The simple blazon is:
"Argent two bars Gules in chief three mullets in fess of the second."
