Palacio Real and Almudena Cathedral are adjacent on a street named Calle Bailén so they visually grab a tourist’s attention. Consequently, it is easy to miss Parroquia Santa la Real de la Almundena, better known as The Crypt. It is located on the south side of the cathedral around the corner on Calle Mayor. Construction of the Romanesque chapel began in 1883 and was finished in 1911. Supporting the interior of Cripta de la Catedral are 558, 10.8 foot columns. Along the floor are burial vaults of Spanish elite. It is a unique experience to visit.
