Action is underway to have Travellers evicted from publically owned land in Jaywick Sands.
A number of caravans, vehicles and trailers moved onto the Jaywick Sands Market site at the junction of Brooklands, Tamerisk Way and Lotus Way site on Wednesday afternoon.
The land was bought last year by Tendring District Council (TDC) and an officer visited the group of Travellers soon after they arrived.
They said they were looking for somewhere to stay for the next two weeks and were told that they could not camp on the market site and enforcement action would be taken to have them moved on.
The Essex Countywide Traveller Unit (ECTU) has been informed and will be speaking to the Travellers to begin the process of eviction.
