• The Nineteenth Century

After the fall of the Serenissima, it was the turn of Napoleon. During this period, the country had to suffer the violence and robberies of the French troops. In 1806 there was an amalgamation of municipalities: Castelcucco, Crespignaga, Monfumo and Pagnano lost their municipal autonomy becoming fractions of the municipality of Asolo. In 1810 the commune was reconstituted. In 1836 the town suffered another earthquake that saw the collapse of the old and unsafe bell tower.

• The Twentieth Century

The municipality of Castelcucco has undergone the following changes: in 1928 the municipality is suppressed and its territories aggregated to the municipality of Asolo; in 1946 the municipality was reconstituted (Census 1936: pop. res. 1581).

• Religious architecture

The bell tower of the archpriest church The archpriest church of San Giorgio is located at a lower point than the town square, contrary to the widespread custom that sees religious buildings placed at the highest points. From a distance, therefore, it is not very visible and only a part of the bell tower can be seen. Inside there are numerous frescoes; the main one is that of St. George, patron saint of the town, depicted in the act of slaying the dragon. Here there is also the fresco in which Saint Lucy gives her eyes to the Madonna. The Tamburini organ dates back to 1942.

Scattered around the town there are numerous capitals dedicated to Santa Lucia, San Bartolomeo (San Bortolo), San Francesco, Santa Margherita, San Gaetano and Santa Giustina.

As of December 31, 2022, foreigners residents in the municipality were 189, i.e. 8.1% of the population. The largest groups are shown below:

1. Romania 55

• Events

Every year, on the second weekend of July, the "Beer Festival" is set up. It takes place in a Bavarian marquee near the Casel, where you can enjoy beer and Bavarian specialties such as hot dogs, hamburgers, sausages and sauerkraut. In conjunction with the festival there are also some merry-go-rounds. Throughout the month of August, on the other hand, in Località San Bortolo there are three festivals for three consecutive weekends, first that of the Alpini, then that of AVIS and finally the Festa del Cacciatore, which in the last period has encountered some problems with animal rights activists.

There is a kindergarten, primary and secondary school, where pupils from neighbouring countries often converge.
