Stone used in building Westminster Abbey?

Westminster Abbey is primarily constructed from a type of limestone known as "Kentish ragstone," sourced from quarries in Kent. This durable stone has been used since the Abbey's foundation in the 11th century, featuring prominently in its Gothic architecture. Additionally, other materials, such as Caen stone from France and various types of sandstone, have also been incorporated throughout its history for restoration and expansion. The combination of these stones contributes to the Abbey's iconic appearance and structural integrity.
