An important historical event was, on April 28, 1799, the Combat of Verderio as part of the Battle of Cassano between the Austro-Russians led by general Josef Philipp Vukassovich (under the overall leadership of Alexander Suvorov) and the cut-off French troops led by general Sérurier, who commanded a division in Moreau's army.

A unified parish for Verderio was established by bishop Charles Borromeo after the Council of Trent, following his pastoral visits in 1571 and 1583.

In 1906 this church would be replaced by a new one built on the same site following a project by architect Giovanni Barboglio; the frescoes that decorate the interior were painted in 1932 by Umberto Marigliani, helped by Vittorio Manini.

Two referendums for the reunification of the two comuni were held in recent times (in 1994 and in 2004) since they already shared many services like the elementary school, the library and the sports hall.

A new referendum was held on December 1, 2013; this time, the majority of both comuni voted in favour of the restoration of a unified Verderio.
