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 Jordaan is a neighbourhood of the city centre of Amsterdam, west of Prinsengracht canal. Originally a working-class neighbourhood, the Jordaan has become one of the most expensive, upscale and desirable locations in the country. It is home to gorgeous historical residential buildings with cute hofjes (inner courtyards), numerous modern art galleries, speciality shops, cafes and restaurants. Rembrandt spent the last years of his life in the Jordaan, on the Rozengracht canal. The Anne Frank House is located on the edge of the Jordaan, on the Prinsengracht canal. Many houses in the Jordaan have a stone tablet on their facade, displaying the profession or family sign of the inhabitants, such as scissors for tailors and a piglet for butchers. See how many you can spot!

In these lovely Gothic-Renaissance cloisters, an elaborate open-sided staircase spirals up to elegant galleries. The round tower alongside was part of the city’s Roman wall.

Across the Douro River, you can visit the port wine caves of Vila Nova de Gaia. There are over fifty wine companies found in this area, with wine lodges offering organised tours and tasting sessions.
