Water feature utilising water from Paddy Freeman's Pond. Probably designed as a waterfall. Has grate in the bottom which drains the water away under the path (HER 5686). This is one example of a number of small "grottos" in the Dene, created at the bottom of steep rock faces where hollowed stones allowed small pools to form. The surrounding rocks were originally planted with ferns and plants with a creeping habit such as Periwinkles.

A stone lined pond with a waterfall, edged with drystone walls. An outflow takes the water out of the pond and under the footpath (HER 5686) to drain away into the Ouseburn. The feature was created through quarrying. This is one example of a number of small "grottos" in the Dene, created at the bottom of steep rock faces where hollowed stones allowed small pools to form. The surrounding rocks were originally planted with ferns and plants with a creeping habit such as Periwinkles.

The construction method of the original paths of Jesmond Dene is still visible in places, particularly on the easternmost upper level path which runs from wooden footbridge near NZ 2611 6662 to the two bridges (HER 5690 and 5691) near NZ 2585 6709. The paths seem to have been constructed of red ash (ferric oxide from the Busy Cottage Ironworks?) hence the name Red Walk, with sandstone edging. This edging is visible where the modern red tarmac is coming away. The tarmac is in fact keeping the edging in place. The paths were resurfaced in asphalt in 1906.

Footbrige. Circa 1870. Sandstone. Ashlar segmental arch with rusticated voussoirs; coursed, squared stone abutments; low, rock-faced parapets ending in low square piers.

1860-62 by John Dobson for Sir William (later Lord) Armstrong as a dining and entertaining room for his international clients and other guests to his estate, as his house was too small for large-scale entertainment. T-plan. Rock-faced sandstone on rubble plinth and 2 courses of pecked ashlar. Roofless. One high storey. Double door. Fanlight with substantial glazing bars between Tuscan pilasters, with sidelights, set in high rusticated round arch. 3 tall windows at each side. Interior has polychrome brick walls. The niches once held statues by Lough. The building included an ante room used as a gallery for Armstrong's art collection. This room had a water-powered pipe organ which utilised water piped from the pond now in Paddy Freeman's fields. The pedestrian tunnels which led under Jesmond Dene Road from Armstrong's house to the banqueting hall still survive (HER 5719). After Armstrong moved to Cragside, the banqueting hall was used as a shelter for visitors to the park. A Gothic style gatehouse was added to the hall by R. Norman Shaw in 1869-70. A Turkey Oak was planted beside the banqueting hall in 1884 when the dene was officially opened by the Prince and Princess of Wales as a public park. The oak is still there. The first event was given in 1862 to the Elswick Works Literary and Mechanics Institute. The hall was used by the Nobles and other local families. A conservation statement was written in 2012.

Mill pond to north of Busy Cottage Corn Mill (HER 4137). Still visible as a slight earthwork. Must have been used as a rubbish tip when it went out of use, as bottles have been found in the fill, along with clinker presumably from the ironworks (HER 5680). The mill pond was lengthened by the mid 19th century, to be filled from a dam and sluice near the Banqueting House Bridge. Excavation in 2010 by ASUD revealed part of the dam for the mill pond. A stone dam was built to shorten the pond in the 1880s-1890s, this is at the end of the present garden. Before the end of the century it was shortened again, with a new dam being made north-east of the present Busy Cottage.

Sluice gate and decorative stone walls to north of Millfield House. This was the site of the mill pond associated with Busy Cottage Corn Mill (HER 4137). The sluice gate allows the mill race to run under Millfield House through a well-constructed stone tunnel. Presumably contemporary with the mill (1855).

Mill race from Mabel's Mill (HER 1402) to Deep Dene House Flint Mill (HER 4033) to Busy Cottage Corn Mill (HER 4137), where it ran into a mill pond (HER 5683). Would have been clay lined originally. A large proportion of the race survives as an impressive earthwork. It is best viewed from the modern wooden footbridge which crosses it at NZ2610 6662. A modern sewer runs through it. Excavation in 2010 by ASUD revealed that the mill race tunnel still carries water from the downpipes on the north side of Millfield House.

Site of an ironworks. The first evidence comes from a Plan of the Manor of Heaton 1785 and Whitehead's Directory of 1790 which lists Thomas Menham, Iron and Brass Foundry, Busy Cottage. In June 1790 Thomas Menham died so in June of that year the Newcastle Weekly Chronicle printed this advertisement - "Busy Cottage Forge and Foundry to be sold to the highest bidder…. There is a good dwelling house, brew house, cold bath, several houses for workmen and a garden well planted with fruit trees…". A second auction sold household furniture, 4 horses, a sow and pigs, sundry garden utensils and the use of the garden until November next. Mitchell's Directory of 1801 mentions Sorsbie at Busy Cottage (family from Sheffield with a background of working with iron). Pigot's Directory of 1811 lists Malin Sorsbie, ironfounder, Busy Cottage. The works were described by Baillie in his 'Impartial History of Newcastle' as "a large manufactory of cast and hammered iron, the property of Mr. Malin Sorsbie". Malin's grandson, Jonathan Sorsbie took over the lease in 1819 but died in 1821, when Frederick Malin Lubbren, the son of Malin's daughter, Mary, took over. He was shortly declared bankrupt. Between 1824 and 1842 it was run by Robert Rayne and David Burn. The partners lived on the site, one in what was probably part of Millfield House, the other in Heaton Dene House, now demolished. It is probable that Rayne and Burn had set up New Busy Cottage works nearer the Tyne in Ouse Street, and they seem to have progressed from making small articles of iron to that of wagons for the colliery lines. In 1832 Thomas Miles Richardson painted an attractive watercolour entitled "Busy Cottage Ironworks". In 1842 the lease was surrendered back to Sir Matthew White Ridley who owned the land. By 1855 the ironwork buildings were converted to a corn mill (see HER 4137). In 1858 two workers' cottages were built, which are probably the Busy Cottages (NZ 2612 6640) we see today. Rayne and Burn lived in Millfield House and Heaton Dean House.

Tim Gates photographed this site in 1978. Roundhouses are apparently evident inside a rectangular enclosure. However it is known that this field and a wide area around it was subject to open cast coal mining in the latter half of the 20th century. This seems to indicate that the feature seen by Tim Gates could not have been a prehistoric site as the site would already have been opencast.
