There is intensive production of wheat, barley and maize and industrial crops such as rapeseed. Today there are still some meadows, some of which are used for breeding sheep and cows.

The 1872 census indicates a population decline in the town. Tromborn is a cereal village, the agricultural crisis of the 1890s and the 1914-1918 war accentuated the rural exodus.

The town is too far from the new industrial centers of the 20th century, many workers and small landowners permanently abandoned their native villages for the cities.

Historical decline between 1936 and 1946 is due to the total destruction of the village at the beginning of the Second World War.

The Church of St. Martin has avant-garde architecture designed by architects Roger Fraisse and Madeline Felix 69 years ago. Its construction was completed in 1955 and renovations were made at the beginning of the 21st century.

A bell dating from 1695 was once located on the steeple of the church of St. Martin. It is still used today on the ground in the straight extension of the nave inside the building. Its presence since 329 years contributes to Tromborn's heritage.

At the beginning of the 21st century, a chapel was built inside the village cemetery.
