Pico do Castelo ({{lang|en|Castle Peak}}) is a {{convert|437|m|abbr=on}} high volcano-shaped peak on Porto Santo Island. The peak is covered with conifers and has a panoramic terrace and a picnic spot. On the top, there is a bust in homage to Schiappa de Azevedo, who contributed strongly to the afforestation of the hill, which was once more deserted, and there are also ruins of a 16th century fortress, symbol of the defense of the population against the continued pirate attacks on the island, during troubled centuries.{{cite web |title=Miradouro do Pico Castelo - Ilha de Porto Santo {{!}} Guia para visitar em 2021 - oGuia |url=https://www.guiadacidade.pt/pt/poi-miradouro-do-pico-castelo-18318 |website=www.guiadacidade.pt |access-date=15 May 2021 |language=pt}}
