Igreja de Nossa Senhora da Oliveira is a historic Gothic church located in the heart of Guimarães, known for its distinctive 14th-century Manueline-style padrao (cross) situated directly in front. The building stands on the site of a 10th-century monastery founded by Countess Mumadona Dias. Its current Gothic structure dates primarily to the 14th-century reconstruction commissioned by King João I to celebrate the victory at the Battle of Aljubarrota. The interior features significant Baroque-style altarpieces and gilded wood carvings added during later renovations. The facade retains classic Gothic proportions, contrasting with the ornate, layered decoration of the interior. It serves as a focal point of the Largo da Oliveira, a medieval square that defines the city's historic core. The church houses the image of Nossa Senhora da Oliveira, which is central to local religious traditions. Its architectural evolution spans from Romanesque origins to its current prominent Gothic and Baroque blend.
