La chabola de la Hechicera (Sorginaren Txabola, 'The Witch's Hut') is a dolmen group located in Elvillar. Three large vertical stones support a large horizontal flat stone. Nine large stones form a chamber in a polygonal shape. The corridor is made of five stones, and is divided into two. The site was probably a funerary construction to hold the remains of the people in the settlement.
It was discovered in 1935 by Álvaro de Gortázar in a fair state of preservation. Jose Miguel Barandiaran explored it partially in 1936, finding two stone percutors, a polished axe of ophite, fragments of pottery and human remains. The stone lying on top was found broken into three parts, but it was restored and replaced in its original position. The findings are preserved in a museum in nearby Laguardia, Álava.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
