A Gruta dos Moinhos Velhos (juntamente com a Gruta da Pena e a Gruta da Contenda), faz parte de uma grande rede de galerias com mais de 11 Km de extensão, constituindo dos mais importantes sistemas subterrâneos do Maciço Calcário Estremenho. Caracteriza-se pela existência de dois coletores paragenéticos fósseis, de diâmetro aproximadamente decamétrico, com afluentes desenhando uma rede dendrítica e um conjunto de galerias semi-ativas de traçado dendrítico a norte e angulado a sul. A zona fóssil tem um desnível de 100 metros e a espessura da zona intermédia varia entre 80 metros a montante e 60 metros a jusante, circulando a água por galerias singenéticas, do quadrante norte para o quadrante sul, em direção à exsurgência da Gruta da Pena.

Podem definir-se quatro fases na evolução do sistema. A primeira é representada por galerias freáticas superficiais, de pequeno diâmetro, a segunda pelo coletor paragenético da Galeria Gémea, a terceira pela Galeria Grande e seus afluentes e a última pelas galerias ativas e semi-ativas dos andares inferiores.

"We had a wonderful time glamping here. It is really peaceful and a great place to enjoy the countryside and the stars at night. And all the little touches, like the homemade jams and fresh bread in the morning, made our stay pefect."

Santo Antonio de Fatima

10/10 Excellent

"Wonderful "

Hotel Estrela de Fatima

10/10 Excellent

"This hotel is perfectly located across from Our Lady of Fatima. The front desk staff spoke English and made us feel welcome. Our room was bright, spacious and spotless. The bed was comfortable with plush pillows. AC was great and quiet. The shower was large, water pressure and temperature perfect. Even the towels had a lovely subtle fragrance that made one feel pampered. Complimentary bottled water, coffee maker with tea and coffee. Breakfast was not free but a reasonable price. Bacon, eggs (both scrambled and hard boiled), small sausages, cheeses, cold meat, cereals, breads, croissants, fruit, juices, packaged gluten free choices and different types of coffee, tea and hot chocolate. The serving staff were excellent and helpful. The pool was small but not overcrowded. Lovely library and space to play chess in the lower level. Paid parking was offered in the underground parking garage. I would highly recommend this hotel and would certainly stay there again. It was a pleasure staying at Hotel Estrella de Fatima. Thank you!"
