Due to its proximity to Quinta da Boa Vista, Caju beach was frequented by none other than the Portuguese royal family. Legend has it that it was there that Dom João VI, famous for not being very fond of contact with water, acquired the habit of taking medicinal baths. Credit for this goes less to the beach's attractions than to a tick, whose inflamed bite is said to have led his doctor to recommend therapeutic dips. Be that as it may, the prince began frequenting a Casa de Banhos (Bathhouse), which is currently one of the only remnants of the old bathing resort. Today, it houses the Museu da Limpeza Urbana, linked to Comlurb.
In that remote past, the presence of the royal family prompted other members of the Portuguese nobility to frequent the beach as well. But the area, today, has nothing aristocratic about it. The beach itself succumbed to the effects of time and to construction in the surrounding area, such as the Rio–Niterói Bridge. The sea waters are polluted. And, along what would be that stretch of shoreline, the yards and parking lots of the Port of Rio unfold instead.
