Station, Grono - (1907-2013) History of the BM With the inauguration of the new San Bernardino motorway (1970), the small, narrow-gauge Mesolcina railway, with no direct connection to the nearby Gotthard railway, appeared obsolete. Starting in 1972—amidst lively protests from the Moesa population—passenger service was discontinued and replaced by P.T.T. buses. After the loss of three out of five electric locomotives due to serious accidents (1969) and the damage to the Soazza-Mesocco section in the 1978 flood, the length of the railway line was significantly reduced on the Castione-Cama stretch. The Rhaetian Railway (which had absorbed the BM between 1942 and 1943 during the severe economic crisis) decided to store its rolling stock in a disused factory in the Grono industrial area, which became a large depot and workshop for overhauling the bogies. This space will be the starting point for the redevelopment of what remains of the Bellinzona-Mesocco electric railway for tourism. In 1985, the Friends of the Mesolcinese Railway Association (AAFM) was founded, and in the summer of 1995 the first Sunday passenger service was inaugurated, a service that continued every summer for the next 18 years. In 2000, the Association transformed into the Tourist Railway Operations Company (SEFT) and recovered an original BM electric locomotive (purchased by the Gotthard Railway Club in 1980), built in Prague in 1909 before being sold to France. In 2003, the Rhaetian Railway also discontinued its freight service, and SEFT was granted another decade of passenger transport. On October 27, 2013, the last tourist run between Castione and Cama took place, definitively ending railway operations in Mesolcina. Since 2020, a Swiss electric locomotive with first and second class seats (1933) and a Belgian freight car (1889) used by the BM have been on public display in the Al Pascolet industrial area on the site of Fratelli Censi SA Tecnica Ferroviaria, not far from the former SEFT depot-workshop.

Stage 7: San Bernardino – Bellinzona An exhilarating descent through the Mesolcina Valley. Eagerly absorbing the mild southern climate. In Mesocco, cyclists enjoy the largest ruin in Switzerland and, at the end of the tour, in Bellinzona, the defiant towers and walls of the tre castelli. Refreshed, they follow the rushing Moësa River out of the lively resort town of San Bernardino. The 46-kilometer-long tributary of the Ticino rises at the San Bernardino Pass and gives its name to the Mesolcina Valley (Misox). Although Italian is spoken in the valley, as in the Poschiavo and Bregaglia valleys, it has always maintained close ties to Graubünden. In the smaller villages, where many of the houses are covered with stone slabs, time seems to have stood still. You hardly stop on your bike during the rapid descent towards the south. Surrounded by rocky cliffs, you roar along a well-maintained road with countless skid marks. The highway, which practically hangs from the mountain, seems a bit surreal. Later, a varied side road leads down to Mesocco. Magnificent views of the valley are revealed. Below the village, perched on a rocky outcrop, are the ruins of the Castello di Mesocco, the 11th-century ancestral castle of the Count of Misox. It is considered one of the most important in Graubünden and the largest in Switzerland. Roveredo is the main town in the lower Misox Valley. And what could be nicer here than a break in a cool grotto, enjoying a typical lunch menu and a glass of local wine? The village also boasts several beautiful 17th-century houses, such as the one designed by local architect and builder Enrico Zuccalli. A secluded stretch follows near Lumino, just after crossing the highway and the river. A forest path leads along the Moësa River over hill and dale. Passing an inviting forest garden grotto and some secluded swimming spots, you reach Arbedo-Castione. Here, the Moësa flows into the Ticino River.

The lake can be bypassed with a mountain bike. Two gates can only be bypassed by stopping and pushing. :-(

Torre di Santa Maria The medieval residential tower was built in the 13th/14th century by the Counts of Sax. Overlooking the valley floor of the Misox, it was part of a territorial control system. The pentagonal tower is inspired by architectural models from central France.

Chiesa San Rocco e San Sebastiano, Grono The church of San Rocco and San Sebastiano, decorated with colourful frescoes, is located in a small square in the centre of Grono. The church, originally dedicated to Saint Bernardine, was a modest chapel probably built at the beginning of the 16th century. In 1660 it was restored and enlarged and dedicated to Saint Bernardine of Siena and Saint Charles Borromeo. Later, in 1690, the sacristy was added and at the beginning of the 19th century the bell tower was built. The nave is characterised by a barrel vault, while the chancel has a cross vault decorated with beautiful baroque stuccoes dating from 1715. The main façade of the church is characterized by colorful frescoes depicting Our Lady of Milk and the patron saints of the church.
