LTrexenta boasts a rich patrimony of splendid monuments, such as La Casa Ruda, a jewel inherited from the past.

An excursion in Trexenta has to include the Nuragic complex of Su Nuraxi di Barumini.
The history of the Nuraghe at Barumini unravels in five phases since the various elements which make up the complex date back to different periods: the oldest part is the central tower (1500-1300 BC); the four internal towers and one external were built later (1300-1100 BC); the defence wall of the internal towers, a second boundary wall and some village huts were constructed between VIII and VI cent. BC; whilst from V to III cent. the huts were inhabited by peasants from the area who modified the existing structures to make them habitable.
Before excavation work began, the Nuraghe was a mound of debris, on the summit of which was found the remains of votive offerings for Demetra and Core, two Roman Gods, suggesting that at some stage it was a Temple in their honour. Later, in the period of the Roman Empire and up to III cent. AD, the hill was used as a burial ground.

Another must while discovering the treasures of the area is a visit to the Nuragic complex of Suelli, "Piscu", an authentic monument of the past which has recently been restored for the benefit of tourists. It consists of ramparts and four towers linked by a walk-way and is surrounded by some huts in round and rectangular stones.

Continuing our tour of the historic monuments of the area, the Menhir Park at Goni is well worth a visit as it is considered one of the most interesting in Europe.
Experts believe that the site was used as far back as the late Neolithic period as a place of worship. The oldest traces date back to the Ozieri Culture (3500-300 BC). About fifty menhir have been found on these hills, all isolated, in pairs, in front of tombs, or aligned from east to west.

Let us end our visit, which obviously cannot include everything, with the "Domus De Janas", or fairy caves, at Corongiu and "S'acqua Salida" at Pimentel.
The necropolis consists of eight tombs, in front of and above which are the remains of ritual fires and cupel (small holes in the rock, designed for the offerings).
Etched on the wall of an inner cell of a tomb there are traces of a drawing of the symbol of the male divinity, the "Bull". One can make out two bull-like heads forming a T, painted in dark ochre and enclosed in a rectangle.
Let us not forget that Senorbì, the chief town of the area, is rich in beautiful monuments, but it is also noted for its museums, such as "Sa Domu Nostra", and above all because it is the home of one of the most important wine co-operatives in Sardinia.
