Ramsgate is mentioned in MP on p78 (2nd ed.).

It is also the place where Wickham makes an unsuccessful attempt to elope with Miss Darcy in P&P.  Ramsgate is a notorious place for secret engagements and elopements.

Ramsgate is in east Kent, England. It was one of the great English seaside towns of the 19th century. Ramsgate's main attraction is its coastline, and its main industries are tourism and fishing.
Ramsgate's harbour is a defining characteristic of the town. The construction of Ramsgate Harbour began in 1749 and was completed in about 1850. The Harbour has the unique distinction of being the only Royal Harbour in the United Kingdom. Because of its proximity to mainland Europe, Ramsgate was a chief embarkation point both during the Napoleonic Wars and for the Dunkirk evacuation in 1940.
There are many Regency and Victorian buildings in Ramsgate.
Landmark building: the Obelisk:

In 1821, King George IV visited Ramsgate. One year later, Lord Liverpool laid the foundation stone for this obelisk, to celebrate the royal status of this harbor. It took a year for this obelisk to be constructed. The locals at the time referred to it as the Royal Toothpick.
