[5] Inside the church, the nave has a double hammerbeam roof, with carvings of the apostles, important figures in Ipswich history, and other designs.

[4] The current St Mary's building was built between about 1450 and 1550, on the site of an earlier church dating back to the 1200s, in the dockland area of the town, the centre of the merchant community.

Over the years, flooding of the church has caused structural problems and, in an attempt to prevent this, the vaults were filled with concrete during the 19th century.

The Trust has organised structural repairs to the church, in particular to deal with the flooding, as the salt water was causing decay of the columns of the arcades.

[7] In 2010 plans were made for the church to be converted into a mental health wellbeing centre, run by Suffolk Mind, assisted by a grant from the Heritage Lottery Fund.

[10] River Church runs regular Alpha courses which had been developed by clergy at Holy Trinity Brompton .These aim to be more accessible by offering free food, short talks, and live music.
