Nominees so far include the Avebury landscape and Salisbury Cathedral - setting up a battle between north and south for the top spot.

Cley Hill, near Warminster

Other nominees include a medieval chessman discovered during an archaeological dig in Ivy Street, Salisbury (now on display in Salisbury Museum), and Alvediston as seen from the tomb of former British Prime Minister Sir Anthony Eden in the village churchyard.

Sir Anthony Eden lived in the village following his retirement from politics.

Green Lane Wood, Trowbridge, the Roman villa in Bradford on Avon, Castle Combe village, the hill forts around Warminster, Malmesbury market cross and Stonehenge have also featured among the nominations.

The poll is part of Window on Wiltshire's Heritage, an innovative £425,000 project - run by Wiltshire County Council and funded by the New Opportunities Fund - to set up a major web-based resource revealing the county's history and culture.
