lavradores (farmers) set up "Póvoa" in the coast. Argivai is divided by the Santa Clara Aqueduct, the second-largest aqueduct in Portugal, construction started in 1626. The old areas of Mariadeira, Regufe, Penalves, and Gândara have modest development, possess different topologies and are residential with small central areas. The Regufe Quarter has as symbol the Regufe Lighthouse, a sample from the 19th century iron art. Aver-o-mar is the northernmost urban coastal district and also of residential nature, with the exception of Santo André also known as Quião, which keeps an untouched fishing character recognized by family homes that have grown up in a spontaneous way. Of the diverse religious buildings the 18th-century Baroque churches are prominent: the Parish Church, the Church of Our Lady of Sorrows and its six chapels, and the fishermen Lapa Church, with its curious Lapa Lighthouse. On the other hand, Misericórdia Church and the Basilica of the Sacred Heart of Jesus denote the preference for the Neoclassical style at the end of the 19th century. The Romanesque revival style can be seen in São José de Ribamar. Beaches and parks Póvoa de Varzim's beach is a stretch of golden sands, forming sheltered bays and divided by rocks. Most beaches in the city are family-oriented such as Redonda, Salgueira or Lagoa Beach and during the summer period it can get crowded while those away from the city core, such as Santo André, are less crowded. Salgueira and Aguçadoura are surfing beaches. Located near a camping park, Rio Alto Beach is chosen by naturists given its difficult access and the privacy offered by the sand dunes. The most important and popular green space is Póvoa de Varzim City Park, an urban park hosting leisure activities. It is almost entirely landscaped including hills, a large island, a lake, ponds and a stream. The city park and other minor parks in Póvoa de Varzim were designed by Sidónio Pardal, a well-known Portuguese landscape architect. It also includes great lawn areas, rustic buildings, amphitheatres and playground structures. It is a popular place for jogging, cycling and birdwatching. It stretches from the A28 motorway to Pedreira Lake. Póvoa de Varzim's most relevant garden squares are Praça do Almada (19th century) and Praça Luiz de Camões (20th century). Near the A28 motorway, there are three small parks: Espaço Agros, Argivai Picnic Park (Parque de Merendas de Argivai), and Travessa de Calves Green Space. Espaço
