Tavares is a municipality in the state of Rio Grande do Sul, Brazil.

It has received some newsworthy highlights as several parts of the municipality were abandoned in the late 1990s due to dune and sea reclaiming the area.

[2] The area has been eventually turned into a reserve, called "Parque Nacional da Lagoa do Peixe" (National Park of the Fish Lagoon).

In Balneário de Lagamarzinho, where once a community of at least 250 families lived, due streets were swallowed by the sea, The only settlement as of 2015 was Balneário de Talha-Mar, where once 180 families lived, only a few remain.

Some other neighborhoods eventually also relocated due to the loss of the other villages claimed by the sea, such as Villa da Barra da Lagoa, 2 km away from the sea, which has abandoned buildings now being buried by the dunes.
