(Translated by Google) Officially, the whole is called Alcázar de Arriba and Porta de Marchena. It is a large fortress that is located to the east of the walled enclosure, at the highest point of Carmona. Pedro I had it restored in the 14th century on top of a previous fortification from the Almohad period, built this one on the remains of another 10th century fortification. It is accessed through the Porta de Marchena, with a large pointed horseshoe arch. It is one of the most enigmatic and least studied gates of the walled enclosure. Through it, you could directly access the enclosure, while also reaching the fortress, connecting the fortress with the field. Its function must have been that of a door of betrayal or an escape door that communicated directly with the outside. The armory is defended by three towers and houses the Parador de Turismo, built on the edge of the Alcores escarpment. From its terrace there are spectacular views of the Vega de Carmona. Pedro I "the Cruel" was the son and successor of Alfonso XI of Castile and Maria of Portugal, daughter of King Alfonso IV of Portugal, and was the last king of Castile of the House of Burgundy. He was born when his brother and heir to the throne Fernando had already died. He was succeeded by the bastard son of King Alfonso and Leonor de Guzmán, Enrique II "the Fraticida", first king of Castile from the House of Trastámara. A handwritten chronicle preserved in the Bibliothèque Nationale de Paris states that Enrique II made the head of Pedro I, nailed to the end of a spear, walk around various cities and castles that still defended the cause of King Pedro I.
(Original)
Oficialmente ao conxunto denomínaselle Alcázar de Arriba e Porta de Marchena. Trátase dunha gran fortaleza que se sitúa ao leste do recinto amurallado, no punto máis alto de Carmona. Pedro I fíxoa restaurar no século XIV sobre unha fortificación anterior de época almohade, construída esta sobre os restos doutra fortificación do século X. Accédese a el pola Porta de Marchena, cun gran arco de ferradura apuntado. Trátase dunha das portas máis enigmáticas e menos estudada do recinto amurallado. Por ela accedíase directamente ao recinto, á vez que se chegaba ao alcázar, conectando a alcazaba co campo. A súa función debeu ser a de porta da traizón ou porta de escape que comunicaba directamente co exterior.O patio de armas está defendido por tres torres e alberga o Parador de Turismo, construído ao fío do escarpe dos alcores. Desde a súa terraza hai unhas espectaculares vistas da Vega de Carmona. Pedro I “o Cruel” era fillo e sucesor de Alfonso XI de Castela e de María de Portugal, filla do rei Alfonso IV de Portugal, e foi o último rei de Castela da Casa Borgoña. Naceu cando xa morrera o seu irmán e herdeiro ao trono Fernando. Sucedeulle o fillo bastardo do rei Alfonso e Leonor de Guzmán, Enrique II “o Fraticida”, primeiro rei de Castela da Casa de Trastámara. Unha crónica manuscrita conservada na Biblioteca Nacional de París afirma que Enrique II fixo pasear a cabeza de Pedro I cravada no extremo dunha lanza por diversas cidades e castelos que aínda defendían a causa do rei Pedro I.
