Floating island La Rota in Posta Fibreno lake, Italy. Natural floating islands are composed of vegetation growing on a buoyant mat of plant roots or other organic detritus. In aquatic regions of Northwestern Europe, several hundred hectares or a couple thousand acres of floating meadows (German Schwingrasen, Dutch trilveen) have been preserved, which are partly used as agricultural land ...
The island is unique among its floating counterparts as its shape is almost perfectly circular. [3] [4] As the island is constantly rotating on its own axis due to the flow of the river beneath it, shearing occurs around its outer edge, eroding the island into its circular shape, similar to ice disks.
[3] [4] Sometimes referred to as "floating gardens," chinampas are artificial islands that were created by interweaving reeds with stakes beneath the lake's surface, creating underwater fences. [5] A buildup of soil and aquatic vegetation would be piled into these "fences" until the top layer of soil was visible on the water's surface. [5]
Floating island typically consists of a meringue served floating on a light custard sauce. Some variations invert this by using a thicker sauce served on top of the meringue instead. To make the meringue, the egg whites are beaten with sugar and poured into a mold that may be lined with caramelised sugar. [10]
Despite a popular image of modernity, artificial islands actually have a long history in many parts of the world, dating back to the reclaimed islands of Ancient Egyptian civilization, the Stilt crannogs of prehistoric Wales, Scotland and Ireland, the ceremonial centers of Nan Madol in Micronesia and the still extant floating islands of Lake Titicaca.

The floating mass of matted vegetation, organic debris, and soil that constitutes a phumdi has a thickness that varies from a few centimetres to two metres. [15] Its humus is black in colour and porous, with a spongy texture. Only 20% of a phumdi's thickness floats above the water surface; the other 80% remains submerged. [15]

The purpose of the island settlements was originally defensive: they could be moved if a threat arose. The largest island retains a watchtower, as do most smaller islands. [citation needed] The Uros Floating Islands as seen from the air, about 5 km (3.1 mi) off the coast of Puno.
