“In what architects describe as a preservation emergency, [Ernest Hemingway’s Havana] house, known as Finca Vigía or Lookout Farm, is tumbling down. An effort to save the finca, an American cultural treasure and an important Cuban tourist attraction, seems threatened by a storm of politics.” An American foundation has offered millions to fund the restoration of the house, but the U.S. government has refused to allow the project to go forward, claiming that it would promote tourism in Cuba, thereby helping the economy of the Communist nation.
