Just imagine: it’s 1923, tons of rock have been quarried for one of the most beautiful neighborhoods in Miami, but now an ugly gash sits in the middle of the village. What to do? How about pump the irregular hole full of water, mosaic and tile up the whole affair, and make it look like a Roman emperor’s aquatic playground? Result: one of the few pools listed on the National Register of Historic Places, a wonderland of coral rock caves, cascading waterfalls, a palm-fringed island and Venetian-style moorings. Take a swim and follow in the footsteps (fin-steps?) of stars like Esther Williams and Johnny ‘Tarzan’ Weissmuller. Opening hours vary depending on the season; call or check the website for details.
