Frost Fairs were held in London
over the frozen
. There were stalls, displays of horsemanship designed to test the ice
, and printer
s who would print you up a record of your attendance on the surface of the river. The first was held in 1564, and the last in 1815. Then, as well as perhaps the incipient global warming
caused by the Industrial Revolution
and the end of the Little Ice Age
, a new bridge
with wider spans changed the flow of the Thames.
The Thames did freeze over once more in the 1890s but it was not considered safe enough to hold a fair on.
