Who’s afraid of a little whimsy? Not us. Dating all the way back to 1559 AD and located in what’s now the Dhow Palace Hotel in Zanzibar, Tanzania, this indoor swimming pool is a piece of history, yet it looks distinctly contemporary. Built-in seating painted in a bright, cheerful hue makes the design scheme especially unique as does the life ring floating on the wall in a similarly bright tone. Built-in shelving behind the seating area provides plenty of plant display opportunities.
