The extraordinary Old City of Bari largely consists of narrow and winding streets, making it a charming place to stroll around. You'll find all the important medieval monuments, such as the Swabian Castle and many churches, including the Cathedral of San Sabino and the Basilica of San Nicola, as well as plenty of bars and restaurants.

One of Nha Trang's most alluring attractions are 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 picknick, others yet enjoying a stylised performance at the on-site outdoor stage. Tickets may be purchased at the counter left of the entrance.
