In stark contrast to the modern part of the city and its industrial port area, the Casco Vello enchants with 19th-century architecture, narrow streets and charming squares of the old town. Casco Vello is an easy uphill hike from the port. Note that some businesses close on Sundays.

Housed inside a former castle, and with splendid park grounds in its immediate surroundings, the Quiñones de León Museum is worth the short trip from central Vigo if only for its well-maintained French garden (some say, a miniature of the one in Versailles). The museum itself contains archaeological artefacts discovered in Vigo and surroundings.

Lodz Modern Art Museum (Muzeum Sztuki) boasts a large and impressive collection of art from the 20th century. The museum is located in a 19th century palace and is now one of Poland’s best art and design museums, featuring works by Chagall and Mondrian.

One of Nha Trang's most alluring attractions is the Po Nagar Cham Towers, an actively used site of religious significance to Cham, Chinese and Vietnamese Buddhists; only 4 towers remain standing (researchers speculate there may have originally been up to 10). Constructed between the 7th and 12th centuries, the towers have a history that goes back to as early as the 2nd century AD when the location was first used for religious purposes. The complex teems with worshippers and visitors daily – you'll likely see some dozing on the hillside, others having a family picnic, and others yet enjoying a stylised performance at the on-site outdoor stage.
