This thread is prompted by the Bokor Park Development theme here: post537135.html#p537135
So as not to drag Bokor Mountain completely off topic, place your candidates for competing White Elephants, megalomaniac constructions, and general ridiculous ideas worldwide here.
I will start off with Qatar: the largest indoor snow area on earth not to offer skiing and snowboarding.

First Indoor Snow Centre Opens in Qatar
A first permanent indoor snow centre has opened in Qatar in the Persian Gulf.

Snow Dunes is located within the Doha Festival City Mall and has an indoor snow area of 9,500 square metres. The centre is themed on an Arabian City and a legend about snow there.

Images of the park’s opening show queues forming as excited locals get their chance to play in the snow where outdoor daytime temperatures are currently in the range of +38 to +42 degrees Celsius. Indoor temperatures are set at -4C

Snow Dunes offers a wide variety of fun snow and ice activities including a tubing hill, a tube roundabout for small children and an ice slide where it’s possible to reach 50kph.

The centre’s website says there are 17 snow guns in the facility.

Skiing and snowboarding are not thought to be offered as a regular activity but it appears from images that they could be possible on the tubing hill if permitted.

In terms of world position Qatar is believed to be the 33rd country to get an indoor snow centre and Snow Dunes is the 98th to be currently operational across six continents. It’s size makes it the 25th biggest and the largest indoor snow area on earth not to offer skiing and snowboarding – all the larger centres do.
