The large Ironstone tower of St Lawrence's Church is a prominent feature of the Towcester skyline. It has probably contained bells since its construction in 1485; today the tower houses one of the finest rings of twelve bells in the world, and keen band of ringers.

In 2000 an automatic carillon complete with nine chiming bells was installed above the ring of twelve. These bells form the Westminster Quarters for the clock, and play various tunes and hymns throughout the day.

Founded in 1981, the Sunday Service band is constituted as the "St Lawrence Society of Ringers", and has ensured that the bells are rung on Sundays before Parish Communion, for Church festivals, and other services as required. Current Ringing times from October 2011 are:

Sundays 1st (Jan, Mar, May, Jul, Sep, Nov)	0945 - 1030
(Feb, Apr, Jun, Aug, Oct, Dec)	Service at Green's Norton
2nd - 4th	0845 - 0930
5th	No Ringing
Practice Night	Friday 2000 - 2130

The band is very strong in terms of both numbers and ability. At the most recent AGM, ringing membership numbered 23; practices cater for all levels of ringing on twelve, from rounds to Spliced Surprise Maximus.

The society is closely integrated with the Church; many members serve, or have served on the PCC in various capacities. The Summer and Christmas dinners are notable Town occasions, with the Mayor and other dignitaries as guests, as well as many ringers from around the country.

Ringers of all abilities are welcome at practice or on a Sunday; Towcester has always been a principal teaching tower in the area, and is a registered "Central Council of Church Bell Ringers Ringing Centre", equipped with a dumb-bell, simulator, and neighbouring conference-style facilities.
