Located inside a huge and decidedly bizarre inter-war building, Warsaw’s National Museum is a must for anyone visiting the city. Dating from 1862 and operating under its current name since 1916, among the huge array of permanent exhibitions, highlights include some wonderful pieces from world antiquity, a wealth of delightful 15th-century Dutch and Flemish paintings and several galleries of Polish art from the 16th century onwards, including some of the best work by the country’s leading early 20th-century artists such as Witkiewicz, Makowski and Szczepkowski. Also on display are some fine examples of furniture and decorative arts inside the Gallery of Polish Decorative Art.

Ticket prices: permanent exhibitions 12/7zł, entire museum 17/10zł. Last tickets sold 45 minutes before closing. Sat Free.
