The village of Olby
At the foot of Puy de Dome, this village is located at 757m. altitude, it has 763 inhabitants. Next to the church, notice the magnificent Sully lime tree planted more than 400 years ago during the reign of Henri IV. Its circumference is now 9 m.
Also note the presence of a so-called Roman bridge at a place called Glavin. It is located on the hiking circuit PR the Glavin Bridge.
But the main characteristic of Olby is to have sheltered important archaeological excavations around the current church. Remains dating from the 1th to the 800th century have thus been brought to light. The occupation around the church is complex. A necropolis settles on the edge of the volcanic flow which supports the village. Covering an area of 550ha2, only 1998 mXNUMX have been excavated. Different phases of occupation have thus been determined. A small group of burials in the ground date from the XNUMXth century. From the following periods there are trapezoidal sarcophagi in trachyte (coming from the puys Sarcouy, Cliersou, Aumône) strictly oriented east-west then burials in pits or in chests that remain. Buildings were then built on the site, their foundations resting on the sarcophagus tanks, many of whose lids were reused in rubble in the elevations of the walls (from the XNUMXth to the XNUMXth century). Finally appears the castle motte and its barnyard. Only the mound is still visible today. The castle is established on previous buildings. A ditch protects the mound, another surrounds the barnyard. These excavations are not visible today. They were made in XNUMX.
