The Nima Sand Museum was opened to the public on March 3,1991. It consists
of a cluster of six glass pyramids. The largest of these is 21 meters high
and and rests on a base whose four sides are each 17 meter long. Inside
this main pyramid stands the world's largest hourglass: 5 meters high and
1 meter in diameter. One ton of sand flows through this hour-glass. This
so-called sand calender is carefully turned over by a group of townspeople
at twelve midnight on the last day of each year. It takes exactly one year
for all the sand to flow through.
