During the first days of war in front of Pallars, Isona village was practically abandoned and was occupied by republican soldiers located in the area. During the nine months that the clashes lasted (April 1938 - January 1939) the town was part of it frontline, so he suffered significantly the effects of combat.

Shortly after ending months of civil war, a report in October 1939 explains the status of the village:

'Village is located next to what was the bridgehead of Tremp, at the foot of the Sierra Comiols, is one of the villages of the province in which most have been felt the destructive effects of war for. During 9 months, was the favorite target of the artillery, situated almost in the same line of fire, only a few hundred meters away. The almost entirely of its houses are in ruins, most of them in absolute ruins.

The artillery bombardment had virtually destroyed the city center, 75% of the buildings were ruins or finally it was necessary to sink them and rebuild them.

In August 1940, the Devastated Regions General Direction, an agency created by the dictatorship that wanted to respond to the problem of the destruction caused by war, decided to intervene. The presence of prison labor was scarce and most of the workers were employees of the agency and Isona inhabitants. The set of buildings that were built 15 years Isona rest, largely, still standing and in use. It is a very different type of architecture in its own building tradition in the area.

Recently, Isona City Council and the Generalitat of Catalonia has set up a route through the main buildings of the village's reconstruction. The panels show photographs and information explaining how the buildings were before the war, how were destroyed during the conflict and how the Franco's agency restored them.

The best example of the 'imperial' architecture is the Town Council building, built in majestic form in a prominent place in Bisbe Badia square. The great tower and the balcony can be seen on the facade are visible elements of the new 'imperial' architecture' works that defined the franco's regime. After the war, the onetime Bisbe Badia square had its three fronts virtually collapsed. Once clear out the area, it was created in the middle of the town a large esplanade to host the new center of town. Thus, the regime built a rectory next to the town hall, and a set of 13 homes aimed at farmers.

One another unique building, apart from local school and the church, is the water tank to get water to the various houses. At present, this element has become a clear visual reference of the village of Isona.

In Isona are few the visible remnants of the intense artillery bombardment that the town suffered. It should be noted in this regard, a house located in front of the Assumption square, overlooking the church square, with the impact of shrapnel in its facade.

The 'imperial' city council

Execution period: April 1948-July 1951

Architect: Gabino Lagarriga

Cost of work: 812.566, 62 pesetas

The building that housed the republican city council was severely affected by war. For this reason, the Devastated Regions General Direction considered necessary to build a new town hall. The building, built majestically in the center of the village, occupied the land of three houses affected by the war, which were expropriated. It was designed following the model defined in towns of less than 1,000 inhabitants and was inaugurated on 9 July 1951.

The main facade is a good example of fascist architecture called 'imperial'; the balcony supported by stone corbels, the great gateway configured for an arch and the tower overhang attached to the front line are common features in the town halls of the time.

The interior of the building housed a garage, a warehouse for municipal services, a jail, the judge's office, the municipal archives, the mayor's office and the secretary office, an office for council members and the secretariat for the customer service, among other units. All main rooms have a fireplace to warm them.
