Baptist Church on Derby Road. SK 4282 4625. © Gervase N. E. Charmley (2011). Facebook.

Central Methodist Church on Market Street. A C19 chapel with a modern frontage (this source dates it to 1839, as Wesleyan). SK 4338 4652. © Gervase N. E. Charmley (2011). By 2026 it was known as The Dwelling Place (Methodist) - link.

The Christadelphian Hall (2023 Streetview) is on Derby Road. SK 4299 4641. Link.

There is or used to be a Friends (Quaker) Meeting House on Hands Road, at SK 4367 4641. Aerial views suggest that it may survive, hidden from Streetview behind later buildings. This source dates it to 1834-1923.

Heanor Free Church on Midland Road. On a map revised no later than 1899 a church called Christians' Meeting House stands on the same site. Whether the present building is of that vintage or a later replacement is uncertain. SK 4307 4679. © Gervase N. E. Charmley (2011). Facebook.

Mansfield Road Methodist Church - a tin tabernacle with a brick skin built over. SK 4415 4680. © Gervase N. E. Charmley (2011). By 2026 it had changed a bit in appearance, and name - now Risen Life Church. 2023 Streetview. Link.

St. Lawrence, the parish church. SK 4359 4644. © Gervase N. E. Charmley (2011). Two interior views - 1, 2, both © Richard Roberts (2026). Link. Grade II listed.

Langley
Derby Pentecostal Church is on Breach Road, and was seen by Streetview in 2024. It seems to be the same building shown as a Christian Meeting House on a map from 1885. SK 4466 4613. Facebook.
A map of 1900 shows a Primitive Methodist Chapel on Laceyfields Road, at SK 4476 4614. It's likely  to be the chapel mentioned here as having been built in 1892. The house on its site was seen by Streetview in 2022. A map of1885 seems to be showing a predecessor on a different nearby site, though as is common on the earliest O.S. maps, it's not obvious which building the label is meant to apply to. It would have stood along this stretch of road - 2024 Streetview, with a building on the left (2024 Streetview) as a plausible candidate.

Marlpool
All Saints on Ilkeston Road. Although only 100 years old this year at the time of writing (2008) the church has been severely damaged twice; once on Christmas Eve 1949, and again in 1995, the second an arson attack. SK 4398 4587. © Patricia Johnson. Link. It post-dates a map of 1900, though was a Mission Church a short walk further south on Ilkeston Road. Was this its predecessor? Demolished, its site is now a car park, seen by Streetview in 2024. SK 4404 4577.
Marlpool U.R.C. on Chapel Street, Marlpool. SK 4419 4578. © Gervase N. E. Charmley (2011). Link. A 1900 O.S. map shows an otherwise unidentified Chapel just yards away at SK 4416 4574, almost certainly its predecessor. The church history page dates the present church to 2004, preceded by one of 1827 (Mount Zion Independent Chapel), that in turn preceded by an Independent Chapel of 1820-2. These latter two on the same site - now part of the church car park - 2023 Streetview.
The cemetery at Marpool has a double Mortuary Chapel, CoE and Nonconformist. SK 4361 4580. It was seen by Streetview in 2024.
