The small and remote island of Skokholm, in Wales, hosts an amazing bathroom well-decorated with paintings of rare birds seen on the island’s nature reserve. Unfortunately over 100 images were lost in a recent renovation but pictures of the paintings are well worth checking out. The BBC has a small slideshow of some of the finest.
If I remember correctly, Skokholm is also where Ronald Lockley carried out the observations for his natural-history classic, “The Private Life of the Rabbit” (the partial inspiration for Richard Adams’s “Watership Down”).
