The Culture Recovery Fund for Heritage is providing £92m with grants from £10,000 up to £3m available for heritage organisations in England.
Funds will be distributed by The National Lottery Heritage Fund and Historic England on behalf of the Department for Digital, Culture, Media & Sport (DCMS).
Non-accredited museums can apply for funding. Accredited museums and those working towards accreditation should apply to the Culture Recovery Fund through Arts Council England.
The deadline is midday Monday 17 August. Decisions on awards will be made from late September.
