The Alcáçovas rattles are of ancient origin, handmade using a complex technique to produce sound, which depends on the thickness of the sheet and the amount of metal used. Each one has a design representing the artisan's mark (known as a coat of arms). They are worn around the necks of certain animals – such as cows or sheep – to guide others while they graze.

The longitudinal nave is divided into three sections, from which the transept arms and the two towers of the façade stand out. The façade is imposing, marked by two symmetrical lateral bell towers. The nave has a full-round vault roof, and lighting is provided by the nave's large windows. The church's entrance portal, dating from 1755, is a meticulous Rococo piece.

It is a 13th-century building that was completely altered in the 16th century to house the chapel of São Jerônimo. Its floor plan consists of two rectangular elements arranged perpendicularly. Notable features include the courtyard portico, a small square opening in the cellars, and three Manueline-framed windows, one of which opens onto a balcony. Also, noteworthy is a single-flight staircase leading to a small portico.

Its exact foundation is unknown. However, it is mentioned in royal documents from 1320. In the 17th century, its main elevation underwent major architectural changes. It features a granite portal, a lintel, a triangular pediment topped by a stone cross, a spire at the north end, and a robust, sharp-pointed bell tower opposite, made of masonry decorated with artistic sgraffito, two eyelets, and an equal number of cast bronze bells, the oldest dating from 1772.

Originally called "Viana de a par de Alvito," the town was repopulated in the 13th century by King Gil Martins. In 1313, King Dinis granted it a charter and privileges and ordered the construction of the castle, which, rebuilt by King João II, still retains the characteristics of the original design. It is a pentagonal monument with cylindrical towers with cruciform arrow slits at its corners.
