proposed project. On April 24, 2005, after severe protest from the Hudson Valley community and environmentalists, St. Lawrence Cement abandoned the Greenport project Since 1992 Scenic Hudson and its conservation partners have contributed to the protection of more than 2,400 acres in the Olana Viewshed. In 2015, a conservation easement protected views from Letterbox Farm Collective, a farm nearby. Restoration and management Olana is managed by the New York State Office of Parks, Recreation and Historic Preservation, with support from the Olana Partnership. Both work to restore Olana to its 1890s appearance. A large museum and archive, part of the original Church property, is open to the public and includes over 700 works by Church as well as thousands of works of art by other artists, including paintings by Martin Johnson Heade, Arthur Parton and John Thomas Peele and numerous works by Church's close friend, the sculptor Erastus Dow Palmer. The archive, open to scholars, contains letters, scrapbooks, bills, receipts and other ephemera. A visitor center is housed in the former carriage house, and an upstairs bedroom has been converted into the Evelyn and Maurice Sharp Gallery, which shows changing exhibitions of artwork drawn mainly from the archival collections. The site was closed during the 2006 season for extensive renovation. Stencils on the walls were stabilized and new carpeting was laid in the Court Hall. Curators and conservators performed rehabilitation work on furniture, upholstery and textiles. Fire safety and climate-control systems were improved. Commissioner Carol Ash said at the re-opening in May 2007, "The installation of new state-of-the-art equipment underscores the commitment of New York State to protect this remarkable historic landmark, and we look forward to once again showcasing the unique collections and extraordinary landscapes of one of our most important cultural resources." The former wagon house in the barn complex now houses educational programs. Future plans include a reconstruction of the wagon house and a stabilization of the main barn, to better fit their role as year-round centers for education. Olana has been cited as an innovative example of a public-private partnership. Olana advocates the preservation of its viewshed by encouraging donations of scenic easements on properties and by discouraging development of industrial projects, such as a proposed cement plant and a proposed power plant. Historiography Olana has been the subject of scholarly study by a succession of students and experts on Church's life. David C. Huntington's cataloging
