The Sé Catedral de Viana do Castelo, also known as the Igreja Matriz, is a fortified Romanesque-Gothic cathedral dating back to the 15th century. It features a distinctive facade flanked by two massive square towers topped with battlements, reflecting its history as part of the city's defensive system. The main portal is decorated with ornate Gothic sculptures of the Apostles. Internally, the structure follows a Latin cross floor plan with three naves supported by sturdy pillars. Several side chapels were added between the 16th and 18th centuries, showcasing diverse artistic influences. The cathedral serves as the seat of the Roman Catholic Diocese of Viana do Castelo. It is constructed primarily from granite, typical of the Minho region's architectural heritage. It functions as an active place of worship while preserving historical ecclesiastical art.
