Colico is dominated byMonte Legnone, at 2,609 metres (8,560 ft) above sea level, and high foothills. Near Colico is an importantnatural reserve, the migration corridor of thePian di Spagna (in the province of Como). The two main waterways of Colico are Inganna and Perlino; the river Adda is a natural boundary between the provinces of Como and Lecco.
The whole area was fortified during the Middle Ages, before the construction of the Fort Fuentes. On the northern Montecchio hill are still visible two guard towers, which formed the so-called Castle Colico, built in theMedieval commune period to control the road from Valtellina. The most important from a strategic point of view was Fontanedo Tower, part of a more complex work of fortification built during the 14th century byVisconti. From the tower it was possible to dominate the Upper Lake, the hinterland of Colico and the area of theLake Mezzola.In defense of the ancient road linking Lake Como with Valtellina, within the territory of Curcio, there is another lookout tower, now transformed into a farm house and called the Curcio tower.
Another part of the defense system is Fortino d'Adda, or Stallone, located out of the border municipalities in the territory of Gera Lario. Its unique structure has slots for the shot of a firearm and a brick bridge that connects the main entrance to the plain. It is currently used for storage. Another fort is placed in the territory ofOlgiasca. It is a casaforte ("stronghouse", or fortified house), which from the top of the hill controls the town below. It is known as the Castle of Mirabello and it is thought to have been built in the first half of the 16th century.
Roccoli, or bird snares, are tree architectures, equipped with nets placed vertically, which surround a sort of stone tower from which the hunting was run. They have long been formidable weapons to catch birds which, at the approaching of winter, migrate southwards. This activity was economically important for Colico, placed on the route of the flocks. Of the many bird snares active until about forty years ago, are still well preserved those located near Piona and along the road that goes up to the Fort Fuentes.
Piona Abbey, located in theOlgiasca peninsula, and home to aRomanesque church built in the mid-11th century, and later enlarged.
The small Romanesque church of San Rocco, originally dedicated to the Saints Fabian and Sebastian, located outside the town on the slopes of Monte Legnone, almost midway between the streams of Inganna and Perlino, at a height of five hundred meters.
Traces of painting, particularly in the apse, are due to an unknown painter from the early 15th century. They include theChrist Pantocrator, flanked by the prophetsJeremiah andIsaiah. A restoration campaign held in recent years discovered an interesting fresco depicting theLast Supper.
Villa Malpensata, located in an isolated position on the lake shore, facing the lake near Olgiasca. It is a nineteenth-century building, which incorporates an older structure.
Villa Osio, located at the end of Via Lungolario Polti and forms the boundary to the shore. It is currently privately owned.
The most important event taking place in Colico is the Italian stage of the World Cup ofkitesurfing. A classical musicfestival,Musica sull'Acqua (Water Music), takes place in Piazza Garibaldi and at the Abbey of Piona. The feast ofSan Rocco is celebrated on 16 August in the homonymous church.
The centre is situated between Piazza Garibaldi, Via Vitali, Largo San Giorgio and Via Pontile. This district contains the main services of Colico. Between Via Municipio and Piazza Alpini are theCity Hall, the library, the church ofSaint George and the main schools. The post office is in Via Villatico.
This district has a long beach, a field of soccer, tennis courts and a school ofsailing.There are a parking lot for motor vehicles, a beach and a school of surfing and kite flying. Near the centre is the industrial zone, home to several factories and the town's landfill.
The mainfrazioni are Colico Piano, Villatico, Curcio (and Palerma locality), Laghetto (composed of Borgonuovo, Corte, La Cà, Fumiarga, Piona localities), Posallo, Fontanedo, San Rocco.They rise around the parochial churches, whose origins go back to various periods. The most ancient is the parish ofNicola of Bari (celebrated on 6 December) in Olgiasca; traces of its building go back to 1252. A document dated 7 November 1593 speaks of the "Parish priory, or Piona Abbey", in charge ofCistercian monks.
The economy is mainly based on tourism, but industry holds a strong second place, as the expanding industrial zone shows, and there is also a large presence of banks. The tourism is mainly focused on the many campsites. The industry boasts leading brands of construction trucks (Iveco) and yachts (Cranchi).
Colico is served by a railway station on theTirano–Lecco railway, which was once electrified withthree phase - 3000 V by theHungarian firm Ganz in 1901. Between 1885 and 1886 Colico was connected withSondrio andChiavenna, although a link withLecco was active only from 1894. The line was then operated by theAdriatic Network, one of three major companies that remained in effect until 1905, year of birth of theFerrovie dello Stato.
