Plans to protect the Royal Marines memorial garden in Deal, Kent, with a £1 purchase of a remaining church wall are being discussed.
A memorial service is held in the garden every year
The church is a backdrop to the garden, created to remember victims of an IRA bomb in 1989, but only the gable wall is left after a fire in 2003.
Dover council says the wall is "an integral part" of the Canada Road site.
Officers have recommended the council buys the wall for a nominal sum of £1, subject to repair by current owners.
The bomb on 22 September, 1989, killed 11 Royal Marines musicians who were practising in the church, which they used as a concert hall.
A memorial service has been held at the site of the explosion every year since, with a minute's silence held at 0822 BST - the time the 15lb bomb went off.
Many of those killed and injured were teenagers
More than 20 other bandsmen were injured in the explosion.
The Royal Marines' School of Music was moved away from Deal in 1996 and some barracks buildings were converted into flats.
Ownership of the garden passed to Dover District Council in 1998.
After most of the building was demolished, the single wall was retained as part of the garden of remembrance.
