ECOMUSEU DAS SALINAS DE RIO MAIOR
As Salinas situam-se a cerca de 3 km de Rio Maior e encaixam-se num vale no sopé da Serra dos Candeeiros. Rodeadas de arvoredo e terras de cultivo são consideradas uma maravilha da natureza, uma vez que o mar fica a 30 km. O conjunto apresenta-se como uma minúscula aldeia de ruas de pedra e casas de madeira, junto à qual se destacam uns curiosos tanques de formas e dimensões irregulares, que a partir da Primavera se enchem de água salgada dando origem a alvas pirâmides de sal.
Embora o documento mais antigo que se refere às salinas date de 1177, pensa-se que o aproveitamento do sal-gema já seria feito desde a Pré-História. A Serra dos Candeeiros é, dada a sua natureza calcária, possuidora de inúmeras falhas na rocha o que faz com que as águas da chuva não fiquem à superfície, formando cursos de água subterrâneos. Uma dessas correntes atravessa uma extensa e profunda jazida de sal-gema que alimenta o poço que se encontra no centro das Salinas, e de onde se extrai água sete vezes mais salgada que a do mar. Esta Jazida de sal-gema ocupa aproximadamente a área da Estremadura Portuguesa, entre Leiria e Torres Vedras, tendo-se formado há milhões de anos, depois do recuo do mar que outrora ocupou a região.
