Five stone wellheads in a row mark a small terrace just inside the Land Gate. They sit over a large rectangular cistern dug in 1574 by the Venetians, who feared a Turkish siege would cut the city off from fresh water and decided to back-up the supply with a 200-cubic-metre underground reservoir.
The cistern saved the city from thirst more than once. Today the square is a leafy public space with cafes and pizza windows on its eastern side, and a low park behind. A pleasant place to sit with a coffee or beer.
