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.

St. Francis Cathedral is one of Santa Fe's historical gems. Serving as the representation of the Southwest's influential past under Catholicism, the Cathedral is a cultural landmark. There are plenty of photograph opportunities with the beautiful interior and classical art. Daily masses are still held.

Båtsmansgränd is a narrow alley located in Gamla Öster, the area above the harbour. Here, you'll find eight quaint, timber-framed boatmen's cottages, constructed in the 1740s. Their simple yet traditional design reflects the era's architectural style. Originally, they served as homes for the boatmen and their families, whom Västervik town was obliged to equip on behalf of the Crown. In the first half of the 20th century, the cottages housed members of the citizens' fire brigade. In the 1970s, these now heritage-listed cottages were converted into a hostel, available for rent in the summer.

A must-see while in Porto is the São Bento Railway Station. More than just a train station, this place is another architectural jewel, among the many others this city boasts. Built by the Portuguese architect José Marques da Silva in 1900, the São Bento Railway Station opened to the public sixteen years later. Its construction took place on the site that once housed a Benedictine monastery, hence the name São Bento. The architecture has a French Renaissance influence, and even though its facade is already quite impressive, its interior is what leaves visitors truly awestruck. The main hall is beautifully decorated–from the ground to the ceiling — with more than 20,000 "azulejos" (Portuguese tiles), which recount important events of the history of Portugal.
