One of Porto Santo’s best-known viewpoints, Miradouro da Portela, offers sweeping views to the north and south. From here, you can take in the entire southern half of the island, including the 9 km-long beach, and see how the island’s low peaks give it a surprisingly open, almost barren feel. On a clear day, Madeira even appears in the distance. A short walk will bring you to the island’s three remaining traditional windmills. Painted white and red with sturdy stone bases, they’re no longer in use but are wonderfully preserved and make a great spot for photos, framed by both the ocean and the inland hills. Portela gets especially magical at sunrise or sunset, when the light casts the bay in golden hues. It’s also easy to combine this stop with nearby attractions like Porto dos Frades natural pools or the Terra Chã hike.

Built between 527 and 565 AD at the foot of Mount Sinai for Emperor Justinian, this monastery later took its name from St Catherine of Alexandria, whose remains are said to rest here. It’s more fortress than church, with thick stone walls guarding the Church of the Transfiguration, the chapel of the Burning Bush, and a monks-only library packed with ancient manuscripts. Inside, you’ll find mosaics, religious ornaments, and some of the oldest illuminated manuscripts in the world on display. Outside, don’t miss Moses’ Well and the garden with centuries of history. The place is open most mornings but closed on Fridays, Sundays, and Orthodox feast days. Still active today, the monastery holds importance across Christianity, Judaism, and Islam, and continues its Greek Orthodox traditions uninterrupted.

Situated within the Diocletian Palace's walls, St Domnius Cathedral is shrouded in history. Created as a mausoleum, it is currently one of the oldest Catholic Cathedral still in use and, with its peculiar octagonal-shaped building, it has an immeasurable artistic value. It was in this Cathedral that the remains of the Emperor disappeared after having rested there for 170 years.
