Task: Question Answering
Input (English): Passage: Weymouth originated as a settlement on a constricted site to the south and west of Weymouth Harbour, an outlying part of Wyke Regis. The town developed from the mid 12th century onwards, but was not noted until the 13th century. By 1252 it was established as a seaport and became a chartered borough. Melcombe Regis developed separately on the peninsula to the north of the harbour; it was mentioned as a licensed wool port in 1310. French raiders found the port so accessible that in 1433 the staple was transferred to Poole.
Melcombe Regis is thought to be the first port at which the Black Death came into England in June 1348, possibly either aboard a spice ship or an army ship. In their early history Weymouth and Melcombe Regis were rivals for trade and industry, but the towns were united in an Act of Parliament in 1571 to form a double borough. Both towns have become known as Weymouth, despite Melcombe Regis being the main centre. The villages of Upwey, Broadwey, Preston, Wyke Regis, Chickerell, Southill, Radipole and Littlemoor have become part of the built-up area.
King Henry VIII had two Device Forts built to protect the south Dorset coast from invasion in the 1530s: Sandsfoot Castle in Wyke Regis and Portland Castle in Castletown. Parts of Sandsfoot have fallen into the sea due to coastal erosion. During the English Civil War, around 250 people were killed in the local Crabchurch Conspiracy in February 1645. 
In 1635, on board the ship Charity, around 100 emigrants from the town crossed the Atlantic Ocean and settled in Weymouth, Massachusetts. More townspeople emigrated to the Americas to bolster the population of Weymouth, Nova Scotia and Salem, Massachusetts; then called Naumking. There are memorials to this on the side of Weymouth Harbour and near to Weymouth Pavilion and Weymouth Sea Life Tower.
The architect Sir Christopher Wren was the Member of Parliament for Weymouth in 1702, and controlled nearby Portland's quarries from 1675 to 1717. When he designed St Paul's Cathedral, Wren had it built out of Portland Stone, the famous stone of Portland's quarries. Sir James Thornhill was born in the White Hart public house in Melcombe Regis and became the town's MP in 1722. Thornhill became an artist, and coincidentally decorated the interior of St Paul's Cathedral.
The resort is among the first modern tourist destinations, after King George III's brother the Duke of Gloucester built a grand residence there, Gloucester Lodge, and passed the mild winter there in 1780; the King made Weymouth his summer holiday residence on fourteen occasions between 1789 and 1805, even venturing into the sea in a bathing machine. A painted statue of the King stands on the seafront, called the King's Statue, which was renovated in 2007/8 by stripping 20 layers of paintwork, replacing it with new paints and gold leaf, and replacing the iron framework with a stainless steel one. A mounted white horse representing the King is carved into the chalk hills of Osmington.
