Off the main road from Porto Christo to Porto Colom, just past a zoo, there's a left turn to Cales de Mallorca - also with the pink sign to Hospitalet Vell. The first site that was clearly marked on our (AA) map as "ruinas prehistoricas"!
Only about 1km down the road, you can see what appears to be a huge wall to the right a way off the road, and soon after there's another sign and a layby in front of a gate where we parked up and walked up the track to the poblat.
Before you actually get to the wall you've seen, a signpost directs you to the left to the foundations of 3 naviforms with a small wood still separating you from the major part of the site.
Back round the wood and the sheer scale of what appeared to be a wall reveals itself as a rectangular monument with the huge blocks of stone typical of the building style of the era. The interior of this monument had inner walls added later.
Exploring round the back, a path leads to the left to a square talaiot with a series of rooms around it and wooden steps to allow visitors to admire the central support pillar of the talaiot and the only known remaining spars which formed the ceiling and second floor - the last century hasn't been kind to the momuments on the island and many have been left to go to ruin, if not ruined intentionally.
Beyond the talaiot and surrounding rooms, there's a heavily overgrown area with more ruins extending into the woods.
