Ordered to be built at the end of the 16th century to defend the coast and the entrance to the Douro River. A fine example of military architecture, the original structure was augmented by modern bastions (17th century) and the entrance gate to the fort (18th century). Currently, the Porto Regional Delegation of the National Defense Institute is located there. It has been classified as a property of Public Interest since June 6, 1967.

Beautiful old fort with a museum inside. The interplay of old and new in the background is also wonderful.

Fort on the way from Foz to Matosinhos. It's easy to walk around the fort, but it's nothing special.

The Nossa Senhora das Neves Fort is also known as the Leça da Palmeira Fort or Matosinhos Castle. Its construction began during the Philippine Dynasty in 1638 or 1639, by order of D. João Rodrigues Sá e Menezes, 1st Count of Penaguião, on the site of Santa Catarina, with the aim of defending that port against threats from pirates and corsairs. After the Restoration of Portuguese Independence, considering its great strategic importance for the defense of the bar, in 1642, the officials of the Porto City Council asked the King to complete the works as soon as possible. A Report from 1701 states that the fortification was still incomplete, although it was armed with four guns and manned by eight soldiers under the command of a lieutenant. It is believed that the fort was completed in 1720.
