The church was formally established as a parish center to serve the growing population of the Estoril area during the 20th century.
The structure incorporates elements of the Pombaline architectural style, characterized by simple, functional design elements implemented after the 1755 earthquake.
It is part of the broader Cascais Parish grouping, which manages several historical ecclesiastical sites across the municipality.
The church retains a dedicated bell tower that remains a visual reference point for the local community.
The Igreja Paroquial de Nossa Senhora da Assunção, also known as the Church of Santo António do Estoril, serves as a primary Catholic worship site in the Cascais municipality. The building features an 18th-century architectural foundation that survived the 1755 Lisbon earthquake. Its interior houses significant religious iconography and traditional Portuguese tile work, known as azulejos. The structure is integrated into the local parish life and continues to function as an active community center. It is situated on a prominent plaza that serves as a focal point for the surrounding Estoril neighborhood. The church remains a well-preserved example of regional religious architecture in the coastal Lisbon district.
