After a spate of people jumping over the fence at the White House, work began this month to make the fence tougher, including new spiky tops. The improvements are temporary until a long-term solution is found, with a design expected later this summer and construction to begin in 2016. The need to keep people out - and maybe livestock in - is hardly new. Ever since Thomas Jefferson in 1801, the White House has been changing the fence.
Here's a look at the history with information provided by the White House Historical Association.

Print of the White House after it was set afire during the War of 1812, circa 1814.
The British were not deterred by Jefferson's fence during the War of 1812, when they set the White House afire. A tornado and heavy rains in Washington put out many of the fires and pushed the British out of the city shortly after the blaze was started.

A semicircular driveway marked by eight stone piers and an iron fence and gates were built across the north front of the White House.
Parts of the wrought-iron fence and stone piers still stand today on Pennsylvania Avenue, with replica gates made from reinforced metal installed in 1976 for increased security.
The stone retaining wall on the south remained until 1873, and mischievous youths often painted their names on the wall.

Public streets were built on each side of the White House.
During World War II, as a major security measure, both West Executive and East Executive Avenues, which run close by each end of the White House, were closed to the public. West Executive Avenue, which runs between the White House and the Eisenhower Old Executive Office Building, was turned into a staff parking lot and never reopened. East Executive Avenue, which runs between the White House and the Treasury Department, was closed to traffic in 1986 and converted into a service road.’
