A reenactment group will give displays of foot drill and musketry at Seaford Museum on Sunday September 15.
The attraction is part of Heritage Open Days (September 12-15) where historic buildings throw open their doors to the public.
Old photos of Seaford will be displayed around the town centre in shop windows as part of the week.
Museum chairman Kay Turvey said: “This group have visited us several times in the past, and have been very popular with visitors, old and young.
“Especially when they fire their “Black Bess” muskets. We are really pleased that they are able to join us again this year.”
The Redcoats 1st Foot Guards (1815) are normally based at Dover Castle, the historic seat of the Warden of The Cinque Ports, but will be at the museum on Sunday.
The museum will offer free admission on Saturday September 14 (2pm to 4pm) and on Sunday September 15 (11am to 4pm).
All the museum’s exhibits and artefacts will be on display. The archives will be open on Sunday from 1.30pm to 4pm.
During the week and with the help of Seaford traders, the museum will display a series of historic photos of the central area of the town.
Museum vice chairman David Swaysland said: “We know that local people find these old pictures really interesting, showing as they do, aspects of the town as it used to be.
“Some of the photos are very old, from the earliest period of photography, but a lot were taken within the living memory of many local people.
“The names of old shops that used to thrive in the town are all but forgotten today, they still bring back many memories, some good some not so good.
“Seaford has always had a thriving town centre for both trade and commerce but these photos demonstrate how our shopping habits have changed, including the loss of some local retailers and the emergence of national or regional shopping chains as well as a number of new local businesses, including an award winning internet retailer; local computer sales and support firms and specialist shops.
“Of course, this initiative relies on the goodwill and support of the local firms and individuals who allow us to show our photos in their front windows.
“We naturally hope local people will continue to support their local traders with their business so that the shops can continue to thrive and the town centre remain buoyant.”
