The first centres established in the current site were Roman, of which there are some remains left even today. Later, under Moorish control, Castro Castle and its population played an important role in their resistance to the Christian Conquest. It was a centre of resistance at various stages in its history. In the 20th century this area had an important role in the Spanish Civil War, being the last Republican stronghold on the Ebro Front to be lost to the Nationals.

Economy

Today the economic activities in the municipality are largely based on rain-fed agriculture and irrigation (which is currently on the rise), at the family level. There are no industrial parks. The companies that do exist also tend to be family-owned. Residents commute to nearby towns to work. In the past, some local male artisans were engaged in the production of Aixereta (esparto braids), while the women made Espardenyes d'Espart (esparto sandals); but these trades have died out in the present day.

What to see

Highlights in Alfondeguilla include the picturesque structure of its steep, narrow streets. The village has two entrances: one on Avenida Betxí and the other via the Calle Mayor (the village's main road), both of which lead to the square, where the San Bartolomé parish church is located. Heading towards the oldest part of the village, known as Castellet, we find the Calvary, on the outskirts of the village, another element of the architectural ensemble.

Landscape

Given the geographical setting of the municipality, it has a mild climate throughout the year, which favours the growth of Mediterranean flora and indigenous fauna. Alfondeguilla has an area of 28.2 km2 and is situated 211 m above sea level. Part of the municipal district of Alfondeguilla belongs to the Sierra Espadán Natural Park.
