Slough Fort is a small artillery fort that was built at Allhallows-on-Sea in the north of the Hoo Peninsula in Kent. Constructed in 1867, the D-shaped fort was intended to guard a vulnerable stretch of the River Thames against possible enemy landings during a period of tension with France. Its seven casemates initially accommodated rifled breech loading guns, which were replaced by the turn of the century by more powerful breech-loaders on disappearing carriages, mounted in concrete wing batteries on either side of the fort. It was likely one of the smallest of the forts constructed as a result of the 1860s invasion scare.All of the guns were removed by 1912, though the fort continued in use during the First World War as a command post. It was decommissioned in 1920 and sold off in 1929. Since the 1960s, it has been used as a stables adjoining a holiday camp. The camp's owners funded a partial restoration in 2012–13 that uncovered previously buried features of the fort.

Thames Hub Airport was a proposed platform-based hub airport located on the Isle of Grain in the Thames Estuary in Kent, whose development has been led by the architect Lord Foster. The idea for the airport was originally included within the Thames Hub integrated infrastructure vision, and the idea of some kind of airport in the Thames Estuary has been discussed since the 1970s. The case for developing the airport as a solution to the question of how the United Kingdom can maintain its global hub aviation status was submitted, alongside many other solutions, to the UK’s Airports Commission in July 2013 by Foster+Partners. In December 2013, the Commission announced its shortlist of proposals for expanding Britain's airports. The Thames Estuary concept was not included on the initial shortlist.In September 2014, the Committee concluded that the Thames Hub proposal had "substantial disadvantages that collectively outweighed its potential benefits and that it therefore did not represent a credible option for shortlisting". They described it as "unfeasibly expensive, highly problematic in environmental terms and would be hugely disruptive for many businesses and communities". It remained off the shortlist.
