The royal couple -- who took the titles of the Duke and Duchess of Sussex when they tied the knot back in May -- will visit the county in southeast England on Oct. 3, Kensington Palace revealed in a tweet on Thursday.

Harry, 34, and Meghan, 37, will see the historic Sussex Declaration and open Tech Park at The University of Chichester in West Sussex.

The visit to Sussex comes just days before Harry and Meghan depart on their first royal tour since their May nuptials. Beginning on Oct. 16, the couple is set to visit Australia, New Zealand, Fiji and Tonga.

Their tour will run the final two weeks of October, before concluding in Rotorua, New Zealand on Oct. 31.

Earlier this month, a source told ET that Meghan is "busily preparing" for the upcoming tour and "doesn't want to make a wrong step."
