A little further beyond the small hamlet of Mombarone d’Asti, following the signs, another, older and unexpected version of the inhabited center arises: the cave houses, structures dug into the tuff, inhabited from the Middle Ages to the first decades of the twentieth century. A dive into the past in a movie-like setting 🎥

Unfortunately, the complete loop cannot be done because you have to go through a private road and the owner is not really available to let you pass, so just after the houses you have to take a road that goes back, shortening the route by quite a bit.

Unusual houses once inhabited and dug into the rock. They can be reached by mountain bike, gravel and above all with good legs.

A cavity in the stone houses an altar and just above the statue of the Madonna. A silent, peaceful place, a few meters from the city center and traffic.

Outside the beautiful and large church dedicated to the Madonna "del Portone", on the left side, there is a delightful pond with fish and turtles overlooked by a stone cavity that houses the statue of the Madonna.

The crutin understood in their natural form (not dug by man in the tuff for the purpose of preserving food and wine) are caves dug into the tuff when the sea reached the level of the mouth of the current caves.

On the hills of the Asti area, in the locality of Carie di Mombarone, a small hamlet northwest of Asti, dug into the embankment of the hills formed by sand-earth deposits (tuff) are the cave houses . These are real houses, all equipped with the famous "crotin" (small cellar), dating from the beginning of the 18th century and inhabited until the beginning of the 20th century. The last inhabitants, from which the houses take their name, were “Gisep d'Carie” and “barba mini”. The houses, albeit shabby, but equipped with all the "comforts" of the time, decorated with utensils, are divided into rooms by brick walls. The rooms are large, the mild and dry climate of the area has favored their habitability, and the abundance of water resources in the area has enabled survival. The stable is distinguished from human habitation, built with a sloping floor for the drainage of waste water and a manger dug into the tuff. The objects of daily work are still present and well preserved. A well was made next to the stable, consisting of a round cistern that was used to collect rainwater and was kept during periods of drought. Between the house and the stable is an inn, which usually served to provide refreshment to travelers and beggars who crossed the valley. The cave houses have been partially restored and furnished by the owners Franco Mario and Adriano and by the association "Quattro passi a nord-Ovest". They can be visited freely, according to the instructions on site.

The 'caves' in the Frinco area are primarily historical structures and natural formations dug into the soft tuff rock, rather than large geological cave systems. These include ancient cave dwellings, such as the Cave Dwellings of Mombarone, and natural tuff caves like I Crutin, which were formed by the sea and later adapted by humans.
Yes, the Madonna del Portone Pond (Asti) features a peaceful stone cavity housing a statue of the Madonna, set within a delightful pond with fish and turtles. It's a quiet, family-friendly spot just a short distance from Asti's city center.
Absolutely. The Cave Dwellings of Mombarone are a notable example. These houses, dug into the hillsides and dating back to the 18th century, were inhabited until the early 20th century. They have been partially restored and furnished, offering a unique glimpse into the past. Another similar site is the Casegrotta Cave Houses, also unusual dwellings dug into the rock.
I Crutin are natural tuff caves in the region. They were formed when the sea reached the level of the current cave mouths and were later adapted by humans, often used as cellars ('crotin') for preserving food and wine. They offer an interesting natural and historical insight into the area.
The Frinco area, part of Monferrato, is excellent for various outdoor activities. You can find numerous hiking trails, such as the moderate 'Castell'Alfero - Frinco Trail', or explore cycling routes like the 'Vineyards of Piedmont – Piazza San Secondo loop'.

The Monferrato region, including Frinco, is generally pleasant for outdoor activities from spring through autumn. Spring offers blooming landscapes, while autumn brings vibrant fall colors and harvest festivals. Summers can be warm, but early mornings or late afternoons are still suitable for exploration. Always check local weather conditions before your visit.
Beyond the tuff caves, the region is characterized by its rolling hills and vineyards, which are part of the UNESCO World Heritage site of the Piedmontese Vineyard Landscapes. While large natural cave systems are not prominent, the geological formations of tuff rock are a defining feature, shaping both the natural landscape and historical human settlements like the cave dwellings.
For broader information about Frinco and the Piedmont region, you can visit official tourism websites. For example, Visit Italy provides general details about what to see in the area.
Given that many of these sites involve walking or light hiking to reach, comfortable walking shoes are recommended. If exploring the cave dwellings, a flashlight might be useful for better visibility inside. Dress in layers suitable for the season, and bring water, especially during warmer months. For any specific trail, check the difficulty and length beforehand.
The Cave Dwellings of Mombarone have been partially restored by local associations and can often be visited freely, with instructions available on site. While formal guided tours might not be regularly scheduled, local groups or tourist offices in the broader Asti province may offer special arrangements or provide more detailed historical context.
