No, it doesn't rain all the time in Britain!
But when it does, it's good to know there's loads to do. From balmy tropical glasshouses to luxurious spas and remarkable art and architecture, there's great fun to be had whatever the weather.
Stay dry in some of the oldest houses and fortresses in the world. Explore classic fairytale castles like the Tower of London with nearly 1,000 years of bloody history, imposing Edinburgh Castle or Cardiff Castle with its sumptuous interiors. If stately homes are more your thing, head to Pride and Prejudice star Chatsworth House or Blenheim Palace, birthplace of Winston Churchill.
