The second biggest castle in Britain (after Windsor), it was built in the late 13th century to secure the area against Welsh attacks from the north. The castle is one of the greatest examples of medieval military architecture displaying an enormous array of defensive structures such as high towers, large moats and barbicans. It is located 15 minutes by train from Cardiff.

The National Trust of Australia Heritage Centre consists of three quaint Queensland houses dating from the last 150 years. All are furnished in the fashion of the period when they were built. The collection of preserved materials from the past, as well as the annual Heritage festival, present an interesting part of local history and culture.

Portland's beer culture dates back to the 1980s when the craft beer movement first began to gain momentum. What started as a handful of breweries has since become a defining element of the city's identity—earning it the nickname "Beervana." Today, Portland is home to roughly 80 (and counting!) craft breweries. A fun way to explore Portland's beer scene is by taking a bike tour that stops at a few local breweries. For those looking to sample a lot in a short amount of time, we recommend Loyal Legion, with 99 local brews on tap, or Apex, where you can taste some of the city's finest craft beers.
