Nowadays, the oldest building in Praia de Valadares is
Sanatório Marítimo do Norte (a sanatorium where diseases like tuberculosis were treated), built in 1916. The construction of that building was the beginning of the development of Praia de Valadares. Before that, it had nothing but agricultural fields and forest. In the 1920/1930s the oldest standing houses in Praia de Valadares were built in Largo da Praia. In 1930 was built the
Clínica Heliântia, a project of the architect
Francisco de Oliveira Ferreira, who also built
Sanatório Marítimo do Norte. In the 60s the first school (Escola da Marinha) was created in Praia de Valadares, replacing an old "Posto de Ensino" (centre of teaching). ==Culture==
