The church was constructed on the foundations of an ancient Islamic mosque, a common pattern in the Reconquista era of the Algarve.
The structure displays a distinct 'Manueline' style entrance, characterized by twisted rope motifs and ornate stone carving.
Extensive archaeological work conducted in the church square has unearthed medieval silos and pottery fragments dating back to the 11th century.
The church interior houses a collection of 18th-century devotional statuary, including a notable image of Nossa Senhora da Assunção.
The church is located at the highest point of the village, serving historically as a defensive lookout as well as a religious center.
Igreja de Nossa Senhora da Assunção, the parish church of Cacela Velha, is a 16th-century religious structure situated on a limestone cliff overlooking the Ria Formosa lagoon. The building was significantly reconstructed following the 1755 Lisbon earthquake, which caused extensive structural damage. Its architecture blends late-Gothic elements with Manueline features, particularly noted in its main portal. The interior retains a set of 17th and 18th-century gilded wood altarpieces, or talha dourada. The site stands on the site of a medieval mosque, reflecting the village's long history under Moorish occupation. Excavations around the church have revealed various archaeological layers, including Roman and Islamic-era remains. It serves as the primary spiritual landmark for this preserved historical village in the Algarve region.
