How To Join

It is a requirement of TheoPhilos membership that members remain active, and the Bureau has the right to dismiss any member who is inactive for more than three years without explanation. There are two main categories of membership for individuals, and a ‘correspondent’ status, as follows:

Correspondents are non-members who wish to be kept informed of events through our email bulletins. To become a correspondent, or to stop receiving notifications, please email theophilos[at]

Associate Membership is the initial category of membership, for ICOMOS members who wish to gain knowledge and build up expertise in the theory of conservation, restoration and preservation. Associate Members are entitled to attend and contribute to our annual meetings, but not to vote, and membership initially runs for three years. 

To apply for Associate Membership of TheoPhilos, please submit the following information via email to theophilos[at]

  • Curriculum Vitae;
  • Two references;
  • Application letter, to include:
    • Brief summary of your relevant experience;
    • Your interest in joining;
    • Your national committee of ICOMOS, with year of registration;
  • Biographical summary (maximum 100 words) for this membership page, if successful.

Acceptance of Associate Members is the responsibility of the Committee. Once received, your application will be reviewed by the Bureau; Bureau recommendations will be collected and presented to the next meeting of the Committee (alongside our conferences, at least once each year in Florence, details on the home page). Please be aware there will likely therefore be a delay between application and confirmation of the Committee’s decision.

Expert Members: Associate Members who have a proven involvement with the Committee can then apply to become Expert Members; this entitles you to attend, contribute to and vote at our annual meetings. Only Expert Members may stand for election to the Bureau.

In addition to Associate and Expert Members, we also accept Non-ICOMOS Members (who will be encouraged to apply for ICOMOS membership), Institutional Members and Honorary Members; we are also open to Institutional Partnerships. Criteria for all classes of membership, and for Institutional Partnerships, are set out in our Bylaws.

Ethical Statement

Please note that we expect all members of Theophilos to subscribe to the ICOMOS Ethical Principles, as adopted by the 18th General Assembly (Florence, 2014) and amended by the 20th General Assembly (Online, 2020). This document provides a useful statement of principles for ICOMOS members, clarifies ethical conservation standards and principles, and outlines our practical responsibilities toward both cultural heritage and our fellow members. All members and applicants should familiarize themselves with this document.
