Hardly an architectural term as it so vague. The Tudor dynasty ruled from 1485 to 1603, but a Tudor-type window can be any window with wooden (often dark wooden) frames, normally leaded panes, that forms part of a timber-framed building.
Many Canterbury examples are heavily restored, or have been removed form other buildings.
