The Heritage Alert process uses ICOMOS’ professional and public networks to promote the conservation of cultural heritage and draw attention to the threats which it confronts and to promote good conservation solutions.

ICOMOS recognizes that publicizing and defining such matters requires a high degree of responsibility. The assessment of situations leading to a Heritage Alert being issued by ICOMOS will therefore be pursued with ethical rigor and accuracy. ICOMOS is by its nature multi-disciplinary, with expert members worldwide.

ICOMOS and its International Scientific Committee on 20th Century Heritage (ISC20C) is issuing a Heritage Alert to respond to the imminent risks of demolition and alterations that could diminish the character of 20th-century heritage in the Serbian capital, more specifically the Dobrovićev Generalštab and the Belgrade Fair complex.

ICOMOS, together with its Japanese National Committee, is issuing a Heritage Alert to stop the construction plans threatening the integrity and scientific value of the archaeological remains of the First Moji Railway Station complex in Kitakyushu City, Japan. ICOMOS demands a reassessment of the development plan and a comprehensive conservation of the remaining sections of the complex.

ICOMOS, together with its Norwegian National Committee and the International Scientific Committee on Rock Art (ISC-CAR), is issuing a Heritage Alert, to stop the planned stone quarry on Aksla mountain, close to the Vingen rock art area, that will damage this remarkable site and its pristine surrounding landscape, unchanged for over 6000 years. Thousands of petroglyphs from the Stone Age can be found in the area, providing unique insights into past narratives.

Following the 2019 ICOMOS Heritage Alert, issued in response to the delisting of this internationally recognised modernist exhibition hall and the political pressure to demolish it in favour of a new museum building, ICOMOS welcomes recent indications that plans for such demolition have changed. The winning design of the architectural competition, selected from among 5 proposals, for a new museum that also preserves the existing hall was published on 11 January 2024.

ICOMOS, together with its Japanese National Committee, is issuing a Heritage Alert to stop the destruction of approximately 3,000 trees and loss of open park space in Jingu Gaien, Tokyo, Japan. ICOMOS strongly warns against the construction of skyscrapers in a world-renowned park, without consultation with citizens and stakeholders. The redevelopement project is scheduled to begin in September.
