Starting at Splash Point: Before you start you may like to take in the view of Seaford Head. Walk a few steps eastward and you can access the groyne for a glorious view of the head to the east and across Seaford Bay to the west.

The broken groyne in the picture protected the old sewer outlet into the sea in the 1880's before the new pumping station was installed. The Head rises to some 283 feet (86 metres) and was topped by the earthworks, now largely lost to the sea, part of an Iron Age hill fort and evidence of subsequent Roman occupation. According to Historic England the earthwork is not a promontory fort but the remains of a Iron Age hill-fort. It is shown as complete in a map of 1587 when, as Burdyck Hill, it was the site of two Armada beacons, but it has suffered coastal erosion resulting in the collapse of the whole of the south west portion of the fort into the sea.
The large red brick retaining wall above is not a fortification or a sea defence. It is all that remains of Cliff Cottage, later the Splash Point Hotel. However the East Fort (now lost to the sea) existed nearby from at least 1717 and was located on a shore platform immediately east of the older groyne. Later in 1795 this site was referred to as "Chinting" Castle although it appears to have been abandoned by this time,
Turn around for a view of the Martello Tower. Before you lose the view inland the large building on raised land is Corsica Hall which has an interesting history. Once the home of the Fitzgeralds family it has since been a teacher training college and is now divided up into private flats. The Seaford Times website has more information about Corisca Hall.
Continue along the promenade passing the Beach Huts towards the Martello Tower
