A door is a movable structure used to open and close off an entrance, typically consisting of a panel that swings on hinges or that slides or rotates inside a space.

When open, doors admit ventilation and light. The door is used to control the physical atmosphere within a space by enclosing the air drafts, so that interiors may be more effectively heated or cooled. Doors are significant in preventing the spread of fire. They also act as a barrier to noise.

They are also used to screen areas of a building for aesthetics, keeping formal and utility areas separate. Doors also have an aesthetic role in creating an impression of what lies beyond. Doors are often symbolically endowed with ritual purposes, and the guarding or receiving of the keys to a door, or being granted access to a door can have special significance. Similarly, doors and doorways frequently appear in metaphorical or allegorical situations, literature and the arts, often as a portent of change.

Valle Maggia (Maggia Valley) is an alpine valley of the Maggia River in Ticino, the Italian canton of Switzerland.

The valley is dotted with small picturesque villages with traditional stone houses, vineyards and dairy farms. In the mid-19th century due to food shortage, economic hardship and an unsustainable population, many families emigrated to Australia and the Americas.

For example, the villages of Lodano and Giumaglio presently have a combined population of around 200 people as compared to 500 in the 19th century. The largest industries of the valley after tourism are stone quarrying and dairy production.

The road from Locarno through the valley leads to others: the Valley of Bosco Gurin, Val Lavizzara, Val di Campo, Val Bavona, Valle di Peccia, Val Sambuco, all part of the Vallemaggia district.

Tall waterfalls are a common sight in the valley as many mountain streams feed the Maggia River throughout its course. In a distance of less than 40 kilometers the Maggia River runs from the foot of an alpine glacier to Lake Maggiore. Beginning with tundra plants at its source and finishing with tropical palm trees at its mouth.
