The climate change adaptation options for built cultural heritage fall into seven categories . Financial constraints are the primary barriers that underpin the first four adaptation options: no action at all, merely monitoring and/or documenting, or annual maintenance . Core and shell preservation, the fifth and sixth categories, are cost effective when they improve the condition of built cultural heritage  , while elevation and/or relocation, the final adaptation options, are extremely costly and might jeopardise the historic value . To date, however, evidence indicates that adaptation actions prioritise archaeological sites . The efficacy of adaptation of historic buildings can be increased through increased and stable funding, incentives, stakeholder engagement, and legal and political frameworks .
