A century-old, single-trunk olive tree enclosed within a square plot bordered by four mouldings bearing the cross of the Order of Calatrava.

It is a three-storey building topped by a brick section housing a clock and bell, which emphasises the building's vertical line. On the eastern side of the same Plaza de la Constitución, further up from the parish church, stands the new Town Hall. Also a regionalist-style building with an elongated layout, its ground floor opens onto a portico of three semicircular arches through which it is accessed, and its main façade is topped by a stone bell gable bearing the municipality's coat of arms.

On either side, two flared circular windows with polylobed outlines embellish the façade, which ends in a continuous moulding leading to the eaves. At the foot of the church, a prominent vertical section rises, topped by a bell gable that stands taller than the rest of the church, divided into two levels for bells: the first with two semicircular-arched openings, and the second with a single opening crowned by a small pediment bearing a cross at its apex. Below, a small door with large voussoirs, aligned with a raised semicircular-arched window above, gives verticality and marks the symmetry of this section. It stands on a small, charming square, the Plaza de la Constitución, raised above its surroundings and bordered externally by a platform with stone pillars topped with balls and linked by a wrought-iron railing. On one corner outside stands a charming stone fountain bearing the emblem of the Order of Calatrava, crowned with broken and mixtilinear mouldings in the Baroque taste.

It consists of a ground floor and two upper sections, with lintelled openings — those on the upper floors being balconies — arranged along a central axis and set between attached pillars. The ensemble is topped by a clock section, crowned by a bell that emphasises its vertical line.

It was built in 1788, as shown by an inscribed stone on its front. It is built of both regular and irregular ashlar. It features a moulding in the form of a pediment, crowned by a stone cross. It has two spouts pouring water into inverted truncated-cone-shaped basins. The whole is decorated with a ceramic tile showing the Sacred Heart in the act of blessing.

Its floor plan features three naves, with the central one wider than the rest. The pillars separating the naves have different layouts, and the arches connecting the central nave with the side naves are semicircular, except in the Gothic area of the presbytery, where they are naturally pointed. A barrel vault covers the three bays of the central nave, which is lined by a cornice and defined by false transverse arches resting on buttresses. The presbytery, built in the 14th century, is constructed of ashlar and roughly hewn stone, though only partially, and is covered by a rib vault with tiercerons, diagonals and a ridge rib. The passage from the nave into the presbytery is emphasised by a large pointed chancel arch with roll mouldings and Gothic capitals decorated with lilies. In contrast due to their more recent date are the sacristy, located at the start of the left-hand side, balanced on the opposite side by a chapel. At the foot of the church stands the choir, raised on Solomonic columns, with a wooden balustrade and three basket-handle arches.

The Salado de Arjona rises in the municipal district of Los Villares and flows through the Campiña region of Jaén in a roughly north–south direction over some 48 km, before flowing into the Guadalquivir river near the town of Marmolejo. The main towns within its basin are Martos and Lopera. It flows into the Guadalquivir within the municipal district of Marmolejo.

It has a single rectangular nave in the shape of a Latin cross, flanked by side chapels and presided over by an apse-less presbytery. The church is covered by a Mudéjar coffered ceiling with a simple tie-and-collar-beam structure, with five ornamented tie beams decorated with strapwork resting on corbels, which, beneath the choir loft, rest on a transverse beam supported by an Ionic column and a wooden bracket decorated with large acanthus leaves. In this same spirit of austerity, the side doorway was built a century later: a lintelled opening with Tuscan pilasters and no decorative elements. During the Civil War, the wooden altarpiece presiding over the Señor de las Aguas was destroyed, and in 1949 another was installed in its place, presiding over the Señor de la Capilla, a name by which this church is also known. The current bell tower, which replaced a bell gable that collapsed in the early 20th century, was built in 1956–57 on a square, prism-shaped base, with a first section featuring vertically arranged oculi on its shaft, framed by a shared moulding; the second section, smaller and octagonal, has pinnacles at its corners and pairs of semicircular arches for the bells, and is topped by a pyramidal spire.

The building is symmetrical, with reinforced corners; its openings are closed with segmental arches, and hierarchy is marked both by the entrance door, emphasised by the access steps, and by the main balcony, from which commemorative events are presided over.

Located in the Plaza del Ayuntamiento. Former mansion of the lords of Ibros. Its structure is still original and stands out above all for its monumental façade and the original stone flooring, which remains fully intact. Ashlar façade with a coat of arms.
