The Alberto Sampaio Museum contains collections of great interest. Of particular note is the sculpture composed of statues from the 13th to the 18th century, made from both limestone and wood. In the collection of woodcarvings, the 17th-century altarpiece that belonged to the Brotherhood of St. Peter and the baroque supports from the church of the Convent of Santa Clara are particularly outstanding. Painting is represented by some remarkable frescoes and painted panels. The display of ceramics is composed of tiles and faience. The textile section is composed of ecclesiastical vestments and an important collection of samples of different cloths. One of the museum’s most famous pieces is the tunic worn by Dom João I at the Battle of Aljubarrota. Finally, amongst the varied collection of gold and silverware, attention is drawn to the treasury of Nossa Senhora da Oliveira: a series of liturgical instruments (chalices, patens, monstrances, crosses and reliquaries) dating from the 12th to the 19th century.
