John O'Gaunt's Castle

Beaver Dyke Reservoirs were two water supply reservoirs (one of which is still extant), 5 miles (8 km) west of Harrogate in North Yorkshire, England. The main reservoir, also known as Lower Beaver Dyke Reservoir, was constructed in 1890 and had a surface area of 9 ha. In 2008 the reservoir's owner, Yorkshire Water, decided that it was not economic to maintain its ageing structures. It was decommissioned between 2013 and 2015 by breaching its dam and channelling a stream in the bed of the former reservoir. A residual lake of 0.5 ha was retained. The water of the reservoir was relatively nutrient rich, but it was known to suffer from potentially toxic blooms of Blue green algae. The smaller reservoir (also called John O'Gaunts Reservoir due to the proximity of John O'Gaunt's Castle) is still filled with water.

Knabs Ridge Wind Farm is an electricity generating site just south of the A59 road near to Felliscliffe, Kettlesing, North Yorkshire, England. It was the first wind farm to be built in North Yorkshire in over 15 years, and was believed to be the first time that civilian air traffic was considered in the planning permission process.

Royal Air Force Menwith Hill or more simply RAF Menwith Hill is a Royal Air Force station near Harrogate, North Yorkshire, England, which provides communications and intelligence support services to the United Kingdom and the United States. The site contains an extensive satellite ground station and is a communications intercept and missile warning site. It has been described as the largest electronic monitoring station in the world.RAF Menwith Hill is owned by the Ministry of Defence (MoD), but made available to the US Department of Defense (DoD) under the NATO Status of Forces Agreement 1951 and other, undisclosed agreements between the US and British governments. His Majesty's Government (HMG) is entitled to possession of the site and retains control over its use and its facilities, though the administration of the base is the responsibility of the US authorities, with support provided by around 400 staff from Government Communications Headquarters (GCHQ), in addition to United States Air Force (USAF) and US National Security Agency (NSA) personnel. In 2014, the number of American personnel was reduced as part of a streamlining of operations due to improvements in technology.The site acts as a ground station for a number of satellites operated by the US National Reconnaissance Office, on behalf of the NSA, with antennas contained in numerous distinctive white radomes, locally referred to as "the golf balls", and is alleged to be an element of the ECHELON system.The site is one of three main sites operated by the United States across the globe as a major satellite monitoring station and intelligence gathering location. The other two sites are located in America and Australia, having similar roles and working together with RAF Menwith Hill to develop knowledge around American, British and Australian interests. The Australian site is known as the Joint Defence Facility Pine Gap.

Wharfedale was a rural district in the West Riding of Yorkshire from 1894 to 1974. It comprised the northern side of lower Wharfedale, the lower Washburn Valley and several parishes between Leeds and the River Wharfe. Until 1937 it also included a detached part, the parish of Esholt north of Bradford.It contained the following civil parishes: Adel cum Eccup (1894–1928) transferred to County Borough of Leeds Alwoodley (1894–1928) transferred to County Borough of Leeds Arthington Askwith Blubberhouses Bramhope Carlton Castley Denton Esholt (1894–1937) transferred to County Borough of Bradford Farnley Fewston Great Timble Hawksworth (1894–1937) transferred to Aireborough Urban District Leathley Lindley Little Timble Menston (1894–1937) transferred to Aireborough Urban District Middleton Nesfield with Langbar Newell with Clifton Norwood Pool Stainburn WestonIt was abolished in 1974 under the Local Government Act 1972, and split between two new districts. The parishes of Arthington, Bramhope, Carlton and Pool went to the metropolitan district of the City of Leeds in West Yorkshire, with the rest becoming part of the Borough of Harrogate in North Yorkshire.

The Haverah Park experiment was a cosmic ray air shower detection array consisting of water Cherenkov detectors distributed over an area of 12 km2 on Haverah Park on the Pennine moorland near Harrogate, North Yorkshire. The experiment was operated by University of Leeds for 20 years, and was switched off in 1987. Air showers of secondary particles generated from a primary cosmic ray hitting the Earth's atmosphere are spread over many kilometres when they hit the ground. An array allows for detection of secondary particles caused by a single cosmic ray at several detectors. The geographic spread of the detectors allows for calculation of the following: The total number of particles detected can be used to estimate the number of particles in the air shower and from the model of the energy required to generate those particles, the energy of the primary cosmic ray. The difference in the time of arrival of recorded particles at multiple detectors can be used to estimate the arrival direction of the primary cosmic ray.During its operation, many thousands of cosmic ray events were recorded including four exceptional events with energies over 1020 eV. These results were somewhat controversial because they are beyond the GZK limit. Such particles were since observed by other experiments, such as Fly's Eye (Oh-My-God particle) and AGASA.

Swinsty Reservoir is a reservoir in the Washburn valley north of Otley and west of Harrogate in Yorkshire, England. Construction began in 1871 and was completed in 1878. The capacity is about 866 million gallons, with a surface area of 63 hectares. It can be found from the A59 road. The reservoir is below and directly adjoining Fewston Reservoir. The area around the reservoirs is popular with walkers.

St Michael and St Lawrence's Church is an Anglican church in Fewston, a village in North Yorkshire, in England. A church was first built in Fewston in the 12th century, and the mediaeval tower survives. The remainder of the church was rebuilt in 1697, from which time the font also dates. The tower was restored in about 1800, while the church was further altered later in the century. It was grade II* listed in 1987. The church is built of gritstone with a stone slate roof, and consists of a five-bay nave, a north aisle, a south porch, a three-bay chancel and a west tower. The tower has three stages, diagonal buttresses, round-arched bell openings with an impost band, a coved cornice, and an embattled parapet with corner pinnacles. The porch has a shallow segmental arch, pilasters, a projecting band, and a dated keystone, above which is a pulvinated frieze, a cornice, a coped gable with shaped kneelers, and a cross at the apex.
