On 3 August, the promise of immense wealth, fame and success will bring the world’s finest minds together in a bid to solve the mystery of longitude.

To celebrate, the Queen has invited the most promising inventors to present their solutions at her summer residence in Greenwich. There, the many marvellous methodologies, devices, and contraptions competing to win the Longitude Prize will be showcased.

Guests are invited to this participatory and interactive experience, beginning with a celebratory waltz in the Great Hall, before guided tours and presentations commence. Live music will be played on the lawns, where refreshments will be available.
