The Chapel of Sant Josep is located at the beginning of Passeig de Cervantes, at the confluence of Carrer Sant Josep and Carrer Pla de La Font. It is situated in the southern part of the urban area of Pego, near the football field.

The area where it is situated was once an old Moorish district known as Atzeneta or Atzaneta. By the time the chapel was completed, in 1677, the urban growth of the town had already incorporated this district into the urban nucleus.

However, the building that can be seen today corresponds to a significant renovation carried out in the early 20th century. Since the early 21st century, the temple has undergone several interventions that have restored its elements, created annex dependencies, and uncovered original paintings hidden beneath the plaster.

It is a rectangular and elongated building with a double-pitched tile roof. It is attached at the rear and the left side to private residences. The right side, where high windows open, faces Passeig de Cervantes. The façade, which has a small annexed room in one corner, is preceded by a terrace delimited by a low wall. This façade is rectangular, with a stone base, and is divided into two halves by a horizontal stringcourse that runs throughout. Above, there is a ceramic altarpiece with an image of Sant Josep amb El Xiquet and, immediately above it, there is a semi-circular arch with a window that illuminates the choir. The bell gable houses a bell baptised around 1945 as Nostra Senyora dels Desemparats [Our Lady of the Helpless]. The entrance door, adorned with motifs alluding to the titular saint, is framed by a smooth stone portal with a pointed arch.

Inside, the spaces between the buttresses define lateral interconnected chapels. There is the choir and, after that, a sanctuary elevated on a platform with lateral dependencies resembling sacristies. This sanctuary is announced by a semi-circular arch with images possibly contemporary to the foundation of the chapel, which a recent restoration has brought to light after having been covered for more than a century. Other paintings decorate the altar, presided over by an image of Sant Josep with the Child in his arms in the niche of a neoclassical altarpiece.

The chapel regularly holds Mass on Sundays, throughout the year. It also hosts various events and celebrations during the Fallas festivities and the Holy Week.
