The flag was raised in Tower Gardens at King’s Lynn on Monday to mark the start of Armed Forces Week.
West Norfolk Mayor Barry Ayres attended and a short service was given by Canon Christopher Ivory, of King’s Lynn Minister.
The flag was raised by cadets from the army and air forces. It remains until Sunday when it will be lowered to mark the end of the week.
The ceremony was organised by the borough council with the parade led by King’s Lynn Royal British Legion members carrying the standards.
Union flags were raised throughout West Norfolk and at Downham Market, town councillor Vera Botham performed the honours.
Present at the ceremony were Falklands (1982) veteran Brian Wallis with Billie Wells and his two dogs. Mr Wallis, 72, is an ambassador for several charities who has given advice at the House of Lords on heath and support for service personnel.
Tomorrow’s Armed Forces celebration is in Downham town hall from 10am and everyone is welcome to attend.
