An interesting house is the House of the Rich Jew (popularly known for presenting a stone facade instead of being covered with lime, as was typical of humble Jewish houses). In the same Jewish quarter, through one of its houses, it is possible to access the Baluarte de los Pozos. It is a section of wall advanced to the rest formed by two towers, the Tower of the Wells or the Gypsy and the Tower Coraja or the Aljibes. It was a key point to guarantee access to the Ribera water. Also in the Jewry itself, near the Pizarro Gate, you will find access to the Olivar de la Juderia, which consists of a space like a garden or park located at the foot of the wall. If you continue on Rincón de la Monja street, at the junction of the street with Cuesta del Marqués, there are two buildings to highlight. One of them is the House of Durán de la Rocha and the other is the Arab Museum House. When descending by Cuesta del Marqués, you arrive at the lowest point of the Monumental City and the most located to the east. Here you can find the Arco del Cristo, Puerta del Río or the Council (the only door of Roman origin that has persisted in the city). From this point it is possible to visualize the Round Tower and, after crossing the arch, the River Tower. Surroundings When the intramural enclosure could not accommodate more buildings, it was decided to build outside the walls around three fundamental spaces: the Plaza Mayor and the two parishes (Santiago and San Juan). Main square The Plaza Mayor is constituted as the center of the Historic Quarter and gateway to the Monumental City. It emerged as a large space for markets, outside the walls. It is dominated in its east side by a frontal formed by the Tower of Bujaco, the Hermitage of the Peace and the Arc of the Star, being able to see also the Tower of the Pulpits and the Tower of the Yerba. To the south is the Town Hall, built at the end of the 19th century. The rest of the Plaza Mayor is formed by arcades that have their origin in the sixteenth century, although the buildings built on them are of very different epochs. The portals housed different guilds, such as the Pan Portal,
