A tent, used for protection from wind and rain when camping.
Facebook's version of this emoji shows it at night time, under stars, as did previous designs from Apple, Samsung, and Twitter. Microsoft's design does not feature stars, but it does include a crescent moon.
Tent was approved as part of Unicode 5.2 in 2009 and added to Emoji 1.0 in 2015.
