The castle is constructed entirely of brick, held together by high-strength lime mortar instead of traditional stone masonry.
The interior displays intricate plasterwork (yeserías) and painted ceilings characteristic of the Mudejar style.
The fortress is surrounded by a double-walled perimeter with a dry moat that is 16 meters deep in some sections.
Alonso de Fonseca, who commissioned the castle, was a prominent member of the House of Alba and a key figure in the Castilian court.
The structure features a unique layout with a square keep surrounded by a polygonal perimeter wall with corner towers.
The castle served as the backdrop for historical events including the birth of Theodosius I, the Roman Emperor.
The building remains under the stewardship of the Spanish Ministry of Agriculture, Fisheries and Food, currently housing a forestry training school.
The exterior brickwork exhibits decorative patterns typical of the 15th-century Castilian Mudejar aesthetic.
Castillo de Coca is a primary example of Gothic-Mudejar brick architecture, constructed in the 15th century by order of Archbishop Alonso de Fonseca. Unlike typical Spanish castles built atop rocky crags, this fortress sits on a plateau surrounded by a wide, deep moat. The structure utilizes brick rather than stone due to the local scarcity of building stone and the expertise of Mudejar craftsmen. Its defensive system features crenelated walls, barbicans, and a formidable keep. The castle stands within the town of Coca in the Segovia province. Guided tours are mandatory for accessing the interior spaces. The fortification served as both a defensive stronghold and a luxurious palace for the House of Alba. It is currently owned by the Ministry of Agriculture, Fisheries and Food.
