Al-Masjid Al-Haram, literally "the Forbidden Mosque", is one of the three most sacred mosques in Islam, along with An-Nabawi in Medina and Al-Aqsa in Jerusalem, and also the largest in the world. Every year millions of worshippers visit the mosque on their Hajj pilgrimage to perform the Salah, "the act of worship”, and the Tawaf, which consists of seven circular walks around the Kaaba, the sacred building that contains the Black Stone.

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.
