Before the opening of the Cape Cod Canal in 1914，the only way ships could leave Boston was on a route around Race Point—the northern tip of Cape Cod.However，navigation during the 18th century was a nightmare，because the floating cross current(交叉气流) around Race Point caused countless accidents.So building a lighthouse to lighten the place was very necessary.

As early as 1808，the people of Provincetown requested a lighthouse on Race Point，but it took Congress eight years to react when they finally paid $ 8,000 on April 27,1816 to build a lighthouse —Race Point Light，which was located in the town of Provincetown，Massachusetts.It was first built of stone 25 feet high with no foundation and its light was 30 feet above the sea.It was equipped with one of the nation's earliest revolving lights.

Actually，there were two other lighthouses on Cape Cod，but they were hit by a storm in October 1841.In the following year，Race Point Light was examined by I．W.P.Lewis，who realized the light's importance.He said，“The light should be useful to all ships leaving Boston.However，its illuminating power is so weak that people would hardly be able to differentiate it from the lights set on the ships which stay in the bay，or close by.It hasn't played its role as a lighthouse well.”

The result was that old lighthouse was destroyed and a new iron lighthouse with a proper foundation was put up to take its place.The new lighthouse was 45 feet high.Although the original keeper's house was in good repair，it was destroyed too and a new one was built.Today the lighthouse has been automated(自动化)and Race Point Light is still an active aid to navigation.

You can park at Race Point Beach and walk about 45 minutes to the lighthouse.Sunset at Race Point Light is one of the Cape Cod's most popular scenes.And at times whales can be seen in the lighthouse.For reservations to stay one night in the keeper's house at Race Point call(508)487－9930.
