All Saints Greek Orthodox Church

All Saints Greek Orthodox Church, originally a Church of England, was built between 1822 and 1824 by architects William and Henry Inwood. The church is constructed of yellow stock brick with stone at the east and west ends, the latter being painted, and features a stone tower. It has a rectangular plan with an apsed chancel, designed in the Greek Revival style.

The exterior includes a west end with a semicircular portico supported by four giant fluted Ionic columns, which carry an entablature that wraps around the building and is reinforced by pilasters at the west end corners. The cornice has antefixae, and above the portico is a circular stone tower inspired by the Choragic Monument of Lysicrates in Athens. This tower features Ionic columns, an entablature, a drum with clock faces, and a cross finial. There are three square-headed entrances with pilaster surrounds, cornice heads, and round-arched architraves, which include 20th-century wooden doors and reeded panelling above. The north and south facades have round-arched windows with architraves and square-headed surrounds, while the east end apse has round-arched windows linked by impost bands.

Inside, the church has a flat ceiling and five bays supported by Ionic columns that hold galleries on three sides. The interior features classical decorative details influenced by Henry William Inwood's travels in Greece. The chancel and nave are now separated by an iconostasis.

Historically, the church was built as a chapel of ease to serve Lord Camden's new developments and was initially known as Camden Chapel. It was dedicated to All Saints in 1920 and was loaned to the Greek Orthodox Church in 1948.
