A pair of unloved and unsignposted talaiots only yards from the roundabout at the exit from the airport road. Directly under the flight path of everything, I'd guess!
The grid reference is for the better preserved of the two; its more ruinous neighbour is about 50 metres east of here.
Directions: when you come out of the airport, take a right at the roundabout onto the M12 and after about 300 metres, take the narrow left turn just past the first buildings. The road winds round and at the T head, go right. The talaiots are in the field just past the last buildings on the right.
