[1][2] The Visconti Castle of Abbiategrasso was built at the end of the 13th century on the site of a previous fortification (Castro Margazario) near a Benedictine monastery.

After losing its defensive function and being easily reachable from Milan by water along the Naviglio Grande, it became his favorite country mansion.

Bricks were the primary construction material, while the stone was limited to structural or decorative elements, such as the slender columns of the mullioned windows, the brackets (beccatelli), or the Biscione on the façade over the old entrance.

In the following years, the ramparts were obliterated to make space for the new train station while also taking care of some restorations.

[5] Although deprived of the south wing and three towers, the castle is today in good condition and open to the public.
