Harefield Pit is a 1.8-hectare geological Site of Special Scientific Interest in Harefield in the London Borough of Hillingdon. It occupies much of a partially filled-in chalk quarry. It has two entries in the Geological Conservation Review database.It is an important Tertiary site in the London Basin, which displays a sequence through the Upper Chalk, Reading Beds and London Clay. It is the only known source of charophytes in the Reading Beds, and these have potential for correlation with other localities in Europe.Natural England has cast the site as "unfavourable declining" as the Reading Beds are not visible due to covering by vegetation. It is set behind Lovett Road, without public access.

Old Park Wood is a 16.7-hectare (41-acre) Site of Special Scientific Interest in Harefield in the London Borough of Hillingdon. The south-east part is an 8-hectare (20-acre) nature reserve owned and managed by the Hertfordshire and Middlesex Wildlife Trust. The site is ancient woodland which dates back to the Domesday Book. It was part of Harefield Park, which had an eighteenth-century house which later became the site of Harefield Hospital.The hilly site is almost wholly wooded, and one of the floristically richest ancient woods in the London area. Its highlight is the abundance of flowers in spring, with a carpet of bluebells together with yellow archangel, lesser celandine, wood anemone and the rare coral root bittercress (cardamina bulbifera).The site is dissected by small valleys and has a variety of types of soil and plants. The trees are mainly oak, birch, hornbeam and ash. Golden saxifrage and marsh marigolds grow along small streams and there is a pond which is important for dragonflies and invertebrates. There is a good variety of birds, including nuthatch and all three British species of woodpecker.The site lies behind Harefield Hospital. There is no access from the hospital, but a footpath along its border fence from Hill End Road leads to the Herts & Middlesex nature reserve. This may be closed as a developer disputes the right of way. Another footpath between Summerhouse Lane and Hill End Road goes through the SSSI, skirting the northern boundary of the nature reserve. The London Loop goes along this footpath.

Uxbridge power station supplied electricity to the District of Uxbridge and the surrounding area from 1902 to 1962.

Mid Colne Valley is a 132 hectare biological Site of Special Scientific Interest in Harefield in the London Borough of Hillingdon and Denham in South Buckinghamshire. Its main importance lies in its extensive diversity of birdlife in lakes in former gravel pits. The site is divided into three areas. The great majority is in an area of four lakes bounded on the west by the River Colne and on the east by the Grand Union Canal. The river forms the boundary between Greater London to the east and Buckinghamshire to the west, and west of the river in Denham is a small area called Ranston Covert. The SSSI also includes a field called Coppermill Down east of the canal.

The Colne Valley Viaduct is a bridge, under construction as of 2023, which will carry the High Speed 2 railway over the Colne Valley Regional Park and the Grand Union Canal, in Hillingdon, west London. When completed, its length of 3.4 kilometres (2.1 mi) and a weight of 116,000 tonnes will make it the largest railway bridge in the UK. It is one of the largest single civil engineering works of HS2 Phase 1.A contract for the section of the railway pertaining to the viaduct was awarded during 2017 and the design concept was released to the public on 19 January 2018. Preparatory work commenced shortly thereafter, including a compulsory land purchase and the establishment of temporary facilities, including a factory, onsite. Construction of the viaduct commenced during March 2021 with completion of the main deck due to occur during 2024 with full completion expected for May 2025. Protestors have occasionally occupied the site, and allegations over the viaduct's aesthetic and environmental impact upon the area have been made.

The 1948 Northwood mid-air collision took place on 4 July at 15:03 when a Douglas DC-6 of Scandinavian Airlines System (SAS) and an Avro York C.1 of the Royal Air Force (RAF) collided in mid-air over Northwood in London, UK (then in Middlesex). All thirty-nine people aboard both aircraft were killed. It was SAS's first fatal aviation accident and was at the time the deadliest civilian aviation accident in the UK. It is still the deadliest mid-air collision in British history. The DC-6, registration SE-BDA and named Agnar Viking, was on an international scheduled flight from Stockholm via Amsterdam to London's RAF Northolt. The Avro York of the 99 Squadron, with serial number MW248, was on a flight from RAF Luqa in Malta to RAF Northolt. The aircraft were two of four participating in a stacking at Northolt. At the time of the accident, the SAS aircraft was holding at 2,500 feet while the RAF aircraft was holding at 3,000 feet. However, due to an error in the setting of the atmospheric pressure compensation of the RAF aircraft, it may have been lower. At the time of the collision the DC-6 was ascending, as the pilots had minutes before decided to divert to Amsterdam and to leave the stacking.

Savay Farm is a Grade I listed twelfth century farmhouse in Denham, Buckinghamshire, England.The house has a timber frame and red brick nogging.It was granted Grade I status in September 1955, protecting it from unauthorised alteration or demolition.Past owners of the house have included the Durdent Family (1130-1512) after whom the house was once named and Lt-Gen. Gerald Goodlake VC, a veteran of the Crimean War and recipient of the Victoria Cross. Goodlake's medals are currently held in the Regimental Headquarters of the Grenadier Guards in the Wellington Barracks, Westminster. Savay Farm was later lived in by Sir Oswald Mosley, a British politician and the founder of the British Union of Fascists. He lived at Savehay Farm (name used by the Mosleys)with his wife, Lady Cynthia Mosley (nee Curzon)]. On the 23rd May 1940, officers of Special Branch raided Savay Farm in conjunction with Mosley's internment and found a collection of firearms and ammunition.As of December 2016, the house is in private ownership. It is within 300 metres (330 yd) of the proposed path of the High Speed 2 railway, which would pass the house on the 30 metres (33 yd) high Colne Valley Viaduct.

Harefield Road was a proposed London Underground station on the western branch of the Central line beyond its current terminus at West Ruislip. Under the London Passenger Transport Board's 1935–1940 New Works programme, the station would have been built alongside the existing Great Western and Great Central Joint Railway (GW&GCJR) line between West Ruislip and Denham as the penultimate station on the Central line's extension from North Acton.Like many other new stations built by London Underground in the outskirts of the capital, the construction of the station was intended to stimulate new housing developments in what was a rural part of Middlesex. Works on the extension were postponed during World War II and, after the war, green belt legislation was introduced to limit the expansion of urban areas. The area beyond West Ruislip fell within the designated Metropolitan Green Belt, and, as the intended housing developments were no longer allowed, the extension beyond West Ruislip was cancelled.
