Teccio del Tersè, Chestnut drying house in Quiliano, Italy.

The Teccio del Tersè is a small chestnut-drying building of dry-stone walls, no larger than 16 square metres, set in a dense chestnut wood along the path beside the Trexenda stream in the Montagna district of Quiliano. It was used for years by woodcutters and charcoal burners as a shelter and for drying chestnuts.

In November 1943 Gino De Marco, known as "Ernesto", converted this chestnut dryer into a partisan shelter, the first base of the Savonese Resistance. The volunteer group "Calcagno" formed here within the Garibaldi Brigades, including Francesco "Checco" Calcagno. On 19 December 1943 German and fascist troops surrounded the site; Calcagno was captured and shot on 27 December at Forte della Madonna degli Angeli. The unit then took his name.

The name teccio, in local Ligurian tecciu, refers to a small rural drying shed, and this one was used for years by woodcutters and charcoal burners as a shelter and for drying chestnuts. A commemorative plaque on the front wall bears the dates "ottobre 1943 - 25 aprile 1977", marking the memory of the partisan events. A poem by Maurizio Calvo, displayed on a plaque inside, is dedicated to the building.

The site is reached via a 2.1-kilometer trail marked with yellow blazes that begins near a church parking lot. The path climbs steeply with approximately 305 meters of elevation gain, so proper equipment and reasonable fitness are needed for the hike.

The plaque on the front wall reads "ottobre 1943 - 25 aprile 1977", linking the partisan months to Liberation Day. A poem is displayed on a commemorative plaque fixed to one of the walls, but the source article does not name its author. The building was restored in 1990 by the Comune of Quiliano with ANPI members from Valleggia, Quiliano and Vado Ligure, and veterans Leti, Preteni and Pianezzola attended the reopening.
