The Swiss Customs Museum, or Museo doganale svizzero, is a museum located in the Swiss canton of Ticino. The museum is sited near Cantine di Gandria, directly across the Lake Lugano from the village of Gandria, and adjacent to the border with Italy. The museum was formerly a border post on that border, but now forms part of the Swiss National Museum. In the 19th and 20th centuries, smuggling flourished in the mountain valleys of Ticino and Graubünden, and the museum covers the history of this, and the work of customs officers to counteract it. In a modern context, it covers the work of the Swiss Federal Customs Administration and the Swiss Border Guard.The museum has no road access, and is best reached by boat. Boats of the Società Navigazione del Lago di Lugano (SNL) provide several crossings a day to Lugano.

The Moltrasio Formation also known as the Lombardische Kieselkalk Formation is a geological formation in Italy and Switzerland. This Formation mostly developed in the Lower or Middle Sinemurian stage of the Lower Jurassic, where on the Lombardian basin tectonic activity modified the current marine and terrestrial habitats. Here it developed a series of marine-related depositional settings, represented by an outcrop of 550–600 m of grey Calcarenites and Calcilutites with chert lenses and marly interbeds, that recovers the Sedrina, Moltrasio and Domaro Formations. This was mostly due to the post-Triassic crisis, that was linked locally to tectonics. The Moltrasio Formation is considered a continuation of the Sedrina Limestone and the Hettangian Albenza Formation, and was probably a shallow water succession, developed on the passive margin of the westernmost Southern Alps. It is known due to the exquisite preservation observed on the Outcrop in Osteno, where several kinds of marine biota have been recovered.
