As part of New York’s Central Park Conservancy project to reconstruct Grand Army Plaza, the William Tecumseh Sherman monument was brought back to life with newly applied 23.75-karat gold leaf. The monument restoration, included as part of the larger Plaza restoration project, called for the removal and reapplication of gold leaf on Augustus St. Gauden’s 1903 masterpiece. The sculptor favored bright, shining monuments, and disdained the look of bronzing as it darkened with age.

This turn-of-the-century lighthouse, also known as Hockomock Head Lighthouse or Swan’s Island Lighthouse provided fisherman and their schooners a beacon for safe travel in busy Penobscot Bay (ME, USA) starting in 1872 and still acts as a navigation aid today.

In 1994 the US Coast Guard deeded the light station to the Town of Swan’s Island and by 2000 the Friends of Swan Island Light began working on a long-needed preservation plan. The plan called for adaptive public use while restoring each of the four buildings including the light tower.
