These aerial photographs, taken by Eddie Mitchell, show eight caravans and several other vehicles on the seafront park.
The caravans were reportedly also seen on Hove Lawns on Wednesday evening, July 20.
On Thursday afternoon a Brighton & Hove City Council spokesperson said “As soon we were made aware of the Hove Lawns encampment we arranged for a joint visit with the police to take place as quickly as we could.
“After making welfare checks a notice was issued asking the group to leave by 6pm.
“This notice directed them to the council’s traveller site, which offers good facilities and access to health care if it is needed.
“The encampment is now in the process of leaving Hove Lawns.”
