Clearly signposted from the 389 between Bitti and Budduso; there's a left turn (if heading north) a couple of km north of the junction to/from Nule and Benetutti. Then 3km on single track lane, but actually a reasonable road and signposted all the way.
The site is open 09:00-13:00 and 15:00-19:00 (Sundays 09:30-13:00 and 14:30-19:00) with 3 guided tours run in each half day. Entry is 3.10 euros for adults with various reductions available. The ticket office is the hut on the carpark; we signed the guest book and were lent a plan of and guide to the site. There'd only been one other visitor all day, and unsurprisingly, we had the place to ourselves for the afternoon.
The complex covers 7 hectares, in a beautiful, if rather windy, spot, with cork oaks and clearings with dappled sunlight. About 20 huts are visible, though there are over 100, and there are 3 temple buildings and a sacred well, each listed separately. The grid reference given for the whole site is that of the entrance to it.
Straight in front of you, the first thing you see is the sacred enclosure with a couple of small huts beyond it, and the megaron temples to the right; following the path ahead goes to the main part of the complex, with the rectangular temple and holy well. The other main features here are huts with niches and hearths, and low benches round their interior walls; one hut is unusual in that is has a central dividing wall, and there's also the "great hut" divided into rooms.
Wow! Until visiting Santa Cristina I'd not been to any holy wells anywhere, and much as that one had impressed me with its sharp lines, this just, well, words just about fail me to describe how stunning this place is.
Check out the pictures!
The well itself is a tholos construction with steps up - to a long passage guarded by betili, with steps / seats to the left and a bank to the right with a path along the top - and leading on to the most spectactular amphitheatre with banked seating all the way round and a clearing beyond that.
Was water brought to the waiting "congregation", or was a journey made from the amphitheatre to the well? Which ever way, the passage had an electric sensation about it ....
By far, my favourite place of the trip. I could have spent hours here.
The third temple at Romanzesu is different in that it's rectangular (you'd never guess from its name!) with its entrance half way along one of its longer sides. It's in the lower part of the site, in the trees to the right as you head towards the well.
The first megaron temple is near the entrance and sacred enclosure. It has a vestibule and then the main room with an L shaped stone bench round 2 walls and a place for offerings. The back walls of the temple are extended, as we saw at Serra Orrios, and the information boards show the structure originally with a steeply pitched roof.
