More than just a bookstore, Livraria Lello is a historical and architectural masterpiece in downtown Porto. Opened in 1906, Livraria Lello & Irmão as it is also known combines elements of Neo-Gothic, Art Deco, and Art Nouveau styles that comprise intricate woodwork, a large stained glass window bearing the bookshop monogram with the motto "Decus in labore" (dignity at work, in Latin), and a remarkable red spiral staircase, which starts as one set of stairs and splits into two that join in a circular design. The latter is a huge attraction here since it resembles the Grand Staircase from the Harry Potter films, and considering J.K. Rowling was once a Porto resident, there is a high chance this place might have inspired her. Livraria Lello became so popular with tourists that in July 2015 the store started charging a 5 Euro entrance fee and queues can take over an hour. You can purchase tickets on their website.

The dunes of Porto Santo might not be huge, but they’re a fascinating sight. Fine sand, traces of coral, and layered sediment form natural patterns and small ridges, while the backdrop shifts between low mountains and the Atlantic Ocean. This unique ecosystem is one of the few sandy dune systems in the Madeira Archipelago, and it’s just a short walk from the beach.

A stroll around Björkholmen still gives you an insight into how it was in the 18th century. The Björkholmen part of the town can be seen as the other side of the tracks in relation to the parade buildings of Trossö. This is where the first shipyard workers and tradesmen lived in small, low cottages, that sometimes rested directly on the flat rock. The streets on Björkholmen are named after different types of ships and admirals. Enjoy the view over Saltsösund and passing boats.

The Cayman Turtle Centre is a conservation facility and tourist attraction that welcomes hundreds of thousands of visitors per year. Although the facility was initially used to breed the endangered green sea turtle for commercial purposes and still continues to operate as a farming operation, its importance as a research and conservation facility cannot be overstated.
