Come and meet the Ghosts on the Banke at Strawbery Banke’s famous Halloween celebration. Long-dead sea captains, 17th century shopkeepers and wayward pirates haunt the streets of Portsmouth’s oldest neighborhood as you trick or treat safely from house to historic house. Tickets available at the door. $8 per person (adult or child over 1 year old; children 1 or under, free). Half-price admission for members.
