The building dates back to the last decades of the seventeenth century and its construction was commissioned by Count Gianbattista d'Arco; the strong testimony of the noble Arcense family is still visible on the portal where the noble coat of arms of the Andrea branch stands out. Towards the end of the 18th century the building was bought by Giovanni Battista Marosi, a priest of Bolognano, who transformed the structure into a wool building from which the name of the Cloths would be derived. The decision to convert the noble palace into a small wool industry was desired by the priest to face the severe crisis of unemployment and misery that was raging in the country. The wool mill was in business for a few years and once closed it became, for the whole of the 19th century, the seat in the following years of various municipal bodies such as fire station, kindergarten and city theater. At the beginning of the 20th century the building hosted several boys from the Institute of Providence and with the advent of Fascism it changed its name to Palazzo del Littorio. The building - which has taken on its ancient name - is the seat of the Bruno Emmert Civic Library, bibliophile of Arco, and of the Giovanni Segantini Atelier. The sculpture in the internal courtyard of the building by the local sculptor Renato Ischia is dedicated to Segantini. The halls of the atelier are used by the Municipality of Arco as a venue for cultural conferences and exhibitions of artistic and historical interest. The palace also houses the Galleria Civica "Segantini" headquarters Arco of May Museum Alto Garda.
The city develops on the slopes of a rocky cliff from which the magnificent medieval castle dominates the entire Upper Garda valley. The castle was built as a fortified village defended by mighty walls and a good sighting system thanks to the towers on the various sides of the nucleus. The whole complex consisted of the two Renghera towers in the highest part of the cliff, and Grande as well as several buildings such as the prison rondello, the blacksmith's workshop, the cellar, the mill and three cisterns. According to some sources, its construction originated in the Middle Ages, built by the inhabitants of Arco and only later became the property of the noble Arcense family that dominated these lands. The castle was abandoned during the 18th century also following the siege by French troops in the summer of 1703 commanded by the French general Luigi Giuseppe di Borbone-Vendôme. An accurate restoration in 1986 and others in the following years, commissioned and carried out by the autonomous province of Trento and the Municipality of Arco, allowed the discovery and recovery of some cycles of frescoes depicting knights and court ladies of the medieval era. Arco castle attracts thousands of visitors every year offering an enchanting view of the area and a visit to suggestive ruins. According to some, the houses in the historic center, arranged in an arch around the cliff of the ancient castle, give the town its name, another current of thought says that the name derives from the Latin Arx, arcis la rocca, precisely due to the presence of this important fortification work. It strongly resembles (and possibly influenced) the painting Isle of the Dead by Arnold Böcklin.
It is near the Collegiate Church of the Assumption. It was consecrated in 1652 by an Albanian bishop and in 1900 it was, in addition to a place of worship, also a winter health centre. The bell tower was damaged by the bombing of the Second World War. The paintings found in the sacristy represent Sant'Andrea and other saints and the whole church was painted by the local painter Antonio Zanoni.
Located in San Martino, the church was completely rebuilt during the 16th century and inside there are several cycles of frescoes from the Italian Renaissance period.
In the hamlet of Caneve. Its construction dates back to the 14th century.
The arboretum is an area inserted in the previous Arciducale Park wanted by the Archduke Albert of Habsburg, the latter cousin of Franz Joseph I of Habsburg and who established his residence in Arco in 1872 by erecting the Villa Arciducale, and extended to one hectare. The project for the realization of the botanical garden was entrusted in the 1960 to Walter Larcher, professor of botany at the University of Innsbruck. The arboretum is rich in tree and shrub species. The plant species conserved are approximately 150 and come from different geographical areas such as southern and central Europe, eastern Asia, the Americas and African regions.
