There is one central aisle with two narrower ones on either side.
There are columns, each supporting a Gothic arch, either side of the main aisle, six from the back to the chancel.
From there, there are seven steps leading up to the sanctuary with two more columns until the bay-shaped sanctuary.
The bay has three gothic arches around it, separating it from the back east side of the church.
The altar is marble, but the top surface of it has been smashed into pieces since the church was closed.
Around the altar are three sculptures set into the wall.
The centre one depicts angels; the north side one depicts church leaders and saints; and the south side one depicts royalty, all kneeling towards an emblem of the Blessed Sacrament being crowned by the angels.

In the north aisle, confessionals still remain.
The floor in the nave is wooden, while the floor in the sanctuary is tiled.
Some of the windows still survive in the church, because they have protective screens on them.
