The Reverend Thomas Hassall, the first chaplain of the Cowpastures, built Heber Chapel in 1827.Heber was dedicated in 1828 by Thomas Hassall "the Galloping Parson" and his father-in-law the Reverend Samuel Marsden. It is named after Bishop Heber of Calcutta whose Diocese encompassed Australia. The architect is unknown. The Chapel contains the original chancel niche and cedar joinery.
Thomas Hassall remained Rector until his death in 1868. Thomas' brother Samuel died in 1830 and his is the first vault in the churchyard.
The foundation stone for St. Paul's Church was laid in 1840 and the Church was completed in 1842.The Church is built of stone and was designed by Colonial Architect John Verge and John Bibb. It is of a cruciform plan with a tower and stone spire.
The Chapel and Church are situated in a peaceful and picturesque setting with a mixture of trees and stone monuments in the Churchyard.
When Reverend Thomas Hassall (Rector of St. Paul's) died in 1868, "Denbigh" was no longer available as a Rectory (Thomas Hassall and family lived here until his death). It then became necessary for St. Paul's to have its own Rectory. The Rectory was built in 1870, the Architect being G.A. Mansfield.
It is a two-storeyed stone building with a steeply pitched slate roof in which dormer windows are set. The inside joinery is cedar. The small verandah on the northeast side was added in 1882.
