Sertã

Sertã is a municipality in the district of Castelo Branco (sub-region: Beira Baixa), covering 447 km² in 10 parishes. Most of it — 82 % — is forest land (woodland, scrub or natural pasture, according to the COS 2025 land-cover map): there, the strip around each house is 50 m wide.

The map finds 407 villages (groups of at least 10 buildings); the largest are Cernache do Bonjardim, Sertã and Outeiro da Lagoa. 143 of them have forest land on more than half of the 100 m strip around them — among them Porto dos Fusos, Carvalhos and Troviscal.
