Herefordshire Council's county archaeology service is hosting the event called "The Past With Us: Archaeology in Herefordshire 2007".
The day will reflect a busy year for the archaeology service and will look at, among others, the new national gas pipeline, Rotherwas Access Road, the flood alleviation works in Hereford city and the results of an aerial survey project.
Dr Keith Ray, County Archaeologist, said: "This year has been an interesting one for the service and discoveries such as the Rotherwas Ribbon and the excavations being carried out at Credenhill Iron Age Hill Fort have attracted national attention.
"This day gives county residents a chance to find out more about the discoveries made and I hope interested people will come along," he added.
Tickets for the event, which starts at 9.20am, are £6 or £10 to include a light lunch and can be booked by logging onto http://www.courtyard.org.uk/ or by telephoning 0870 1122330.
