[4] In 1897, a church was built in Villars-Burquin and a parish was created in the four municipalities in order to bring their populations closer together.

[7] It is because of these small efforts to create a bond within the region of "Pied-de-la-Côte" that such a large proportion of the population voted yes to the merging of the four municipalities.

[4] After the four municipalities fused in 2011 it gave Tévenon a surface area of 1426 ha (14.26 square km).

The total surface area put it in 41st place on the list of municipalities in the canton of Vaud by size.

Approximately 53% of this area is made up of forests but there are also numerous prairies thanks to Tévenon's high altitude which culminates at 1432m (at la Joux Dessus).

[6][10] The historical population is given in the following chart:[6][11][12][13][14] The entire hamlet of Vaugondry is designated as part of the Inventory of Swiss Heritage Sites.

Villars-Burquin achieved the construction of a fire station, and Fontanezier's budget was devoted to important sums for the installation of a wastewater network for the farms situated on the top of the village.

The bill, which has been demanded by the state, was rather difficult to accept for Fontanezier and they're municipality have had to consider a few years of cushioning.

Vaugondry and Romairon's municipalities didn't have a very good budget, and therefore were not able to assist in the financial cost of the wastewater network.
