The Primate Cathedral of Saint Mary of Toledo (Santa Iglesia Catedral Primada de Toledo), known simply as Toledo Cathedral, is considered one of Spain's most important cathedrals. This 13th-century Gothic landmark was built over the foundations of a former church, which was used as a mosque but was eventually torn down.

The Moorish Mudéjar styles are incorporated into its cloisters and gallery. The paintings by the renowned El Greco are a magnificent work of art that captures one's visual senses.

One of the most outstanding features of the Cathedral is the Baroque altarpiece called El Transparente. Its name refers to the unique illumination provided by a large skylight cut very high up into the thick wall across the ambulatory behind the high altar, and another hole cut into the back of the altarpiece itself to allow shafts of sunlight to strike the tabernacle. This is truly a heavenly vision to behold.

The cobbled alleyways of the plaza takes one to quaint clock shops that specialise in the artistry made famous by Jews from Syria; the enamelled holographic pieces on royal blue are treasured pieces to own.
