The urban nucleus is located in the center of the municipal term. The orographic configuration of the establishment place is presided over by the hill of the Castle and it is limited the south, the east and the northwest by diverse hills. The only routes that the topography leaves free for the urban growth are the north, following the ways of Arahal, Marchena and Puebla de Cazalla, and the west, in the direction of Seville.

During the Muslim domination, the establishment is organized around the fortress, that counts on its own walled enclosure and it is located at the top of the existing hill in the Southeastern sector of the present nucleus. The propitious fort demographic increase that the construction occupies outer slopes of the castle, being protected by a second walled enclosure, that would have three doors (the one from Seville to the west, the one of San Micas to the north and the one of Olvera to the south). Into century XIII, the Christians transform the mosque in church and found to the east of the castle the district of Santa Maria. The topographic barriers mentioned and the little importance of the way of the mountain range (towards Pruna and Olvera) cause that the nucleus is developed towards the north and the west. In first half of century XV, due to the border insecurity, the locality concentrates in the enclosure intrawalls. In second half of this century, to the time that moves away the Muslim danger, the suburbs of Santa Maria, San Miguel and the door of Seville are developed.

In century XVI an important development takes place, being the urban morphology defined to the east by the San Miguel street and its continuation the street Track, to the southwest by the street Race and to the south by the street San Francisco. In both later centuries it continues the strong urban growth towards the southwest and the north. At the beginning of century XIX, the presence of the French troops finalizes with the blast of the castle. In 1.864 the railroad is inaugurated, allowing the communication with Utrera and Seville. The station locates to the north of the nucleus, causing an important development in its surroundings and constituting the catalyst of the growth in that direction that takes place at the beginning of century XX. In the other end, the Alamos street, that opens to passage between the hill of the Castle and the southern hill chain looking for the way of Pruna, has constituted a limit to the growth until end of century XIX.

In years 50 and 60 establishments in the North sector (quarter of the Marsh) and in the south are made, in the small space that allows the topography (San Francisco). In years 70 the quarter of La Paz is already constructed, with isolated blocks that consecrate the direction of linear growth towards the west, following the way of Seville, throughout as they appear the Tree-lined avenue and industrial estate C.E.M.G.S.A. After 1,975 (and towards the east) the Polygon is urbanized by means of public promotion the Farm. At the present time, the more important road axis of Morón is the one that with East-West direction good structure part of the nucleus like prolongation of the highway of Seville. The North sector welcomes some of the most recent promotions, in which the new constructive tipologías are present.

Between its constructions of artistic historical interest they emphasize the churches of San Miguel (Xvi-xviii centuries), San Francisco (century XVI), Our Lady of the Victory (century XVI), San Ignacio (century XVIII), the Favor (century XVIII), Santa Maria of Asuncio'n, Santa Clara and San Juan de God (century XVII), the hermitage of Our Father Jesus of the Gorge (century XVIII), the Cilla of the Town hall, as well as the rest of walls and the Tower of the Tribute.
