Fofos de Belas are a Portuguese confectionery specialty, originating from the village of Belas, in the municipality of Sintra. This traditional sweet consists of a small, light cake, similar to sponge cake, filled with custard and dusted with powdered sugar. Initially known as "Fartos de Creme," Fofos de Belas have over time acquired a prominent place in Lisbon's gastronomy and Portuguese culinary culture.

and in the middle of nowhere there it is, a beautiful colony of cat shelters that match the "modest" little houses in the Belas golf club complex. As it is a private area, the attack on the forest that is being carried out there goes unnoticed, roads destroyed, others (many) created with new constructions in mind :-(
