Preservapedia needs you

The International Council on Monuments and Sites (ICOMOS) (French: Conseil international des monuments et des sites) is a professional association that works for the conservation and protection of cultural heritage places around the world. ICOMOS was founded in 1965 as a result of the Venice Charter of 1964 and offers advice to UNESCO on World Heritage Sites. The idea behind ICOMOS dates to the Athens Conference on the restoration of historic buildings in 1931, organized by the International Museums Office. The Athens Charter of 1931 introduced the concept of international heritage. In 1964, the Second Congress of Architects and Specialists of Historic Buildings, meeting in Venice, adopted 13 resolutions. The first created the International Charter on the Conservation and Restoration of Monuments and Sites, better known as Venice Charter; the second, put forward by UNESCO, created ICOMOS to carry out this charter. ICOMOS currently has over 7500 members. With rare exceptions, each member must be qualified in the field of conservation, and a practicing landscape architect, architect, archaeologist, town planner, engineer, administrator of heritage, art historian or archivist. Its international headquarters are in Paris. (Read more...)

Featured case study

Six logan circle.jpg

Constructed in 1878 from the designs of architect Henry R. Searle, Six Logan Circle is a five-story rowhouse which features a highly articulated façade of green serpentine stone laid up in a veneer of quarry-faced, random ashlar blocks with Pennsylvania red brick trim. Located in the Logan Circle National Register Historic District in Washington, D.C., this building sits directly on Logan Circle, an original open space design element of the 1790s plan for the Federal City by Pierre L’Enfant. Constructed for Naval Commander Allen V. Reed, the property remained a single-family residence until 1940 when the Reed family sold the building. Typical of many of the large residential properties within the district, Six Logan Circle was subdivided and converted into a multiple-unit dwelling after World War II. Over the next forty years the building functioned as a nine-unit apartment complex and received little maintenance during this time. In 1982, the property was purchased by the Six Logan Circle Associates with the intent of rehabilitating the property into six residential units. A major component of the rehabilitation focused on selecting a treatment for the extremely deteriorated serpentine stone façade. (Read more...)

Featured legal case

Paulina Lake (Deschutes County, Oregon scenic images) (desD0149).jpg
In Paulina Lake Historic Cabin Owners Association v. United States Department of Agriculture Forest Service, Plaintiffs maintained vacation cabins in a camp on Forest Service land under a special use permit originally issued in 1934. At the time that the original permit expired, the Forest Service began efforts to change the use of the site. Nevertheless, the Forest Service issued a new special use permit allowing plaintiffs to remain in possession of the camp until 1979. Further extensions of the permit were denied, and in 1980 and 1981 the Forest Service requested plaintiffs to remove the structures so that the Government could retake possession of the land. The Forest Service told plaintiffs that as of June 1, 1981, whatever property remained would become Government property. In April 1981, under prodding by the plaintiffs, the Forest Service applied to the Keeper of the National Register of Historic Places for a determination of the eligibility of the entire camp for the Register. The Keeper decided that the camp was not eligible, and the Forest Service again requested plaintiffs to remove the structures. (Read more...)
