São Félix is located in the civil parish of Laundos, and is a sequence of Serra de Rates mountain range.
Despite its low height, São Félix is easily distinguished in the landscape because it is a significant rise in front of a coastal plain.
The hill is of ancient cult to the people of Póvoa de Varzim, especially the fishermen, as it was used as a reference from the sea.
It is also the main pilgrimage site of Póvoa de Varzim and Vila do Conde, especially important for the fisher community, who walk a 7 km long way from the Matriz Church of Póvoa de Varzim to Senhora da Saúde Shrine.
This myth was used by Braga clergy in order to justify that city's religious leading role in Christian Iberia.
