A ramp leads from Plaça de Sa Font in Sa Penya up to the Portal de ses Taules gateway, the main entrance. Above it hangs a commemorative plaque bearing Felipe II's coat of arms and an inscription recording the 1585 completion date of the fortification – seven artillery bastions joined by thick protective walls up to 22m in height. You can walk the entire perimeter of these impressive Renaissance-era walls, designed to withstand heavy artillery, and enjoy great views along the way.
