The River Leven Valley from Windygates to Levenmouth.
Some evidence of Bronze Age settlements along the banks of the Leven exists. Aerial photographs show remains of ring ditches at Ashgrove and on the north bank of the river, near the United Distillers complex. As well as the remains of the Bronze Age burial site at Ashgrove, there are references to a souterrain having been discovered at Pirnie (Ashgrove) in the mid 19th century. During the construction of the housing scheme at Methilmill the top half of a stone quern of medieval date was discovered.
Records would suggest that there was a small religious settlement on the site of the present Methilmill cemetery, possibly a culdee settlement, during the 12th century. A church stood on this site for several centuries until it fell into ruin towards the end of the last century and was replaced by the first Methil Parish church built in Lower Methil. The small churchyard can still be seen - part of the much larger and newer Methilmill cemetery - with headstones dating from as early as the late 18th century.
Further up the river stood the tiny village of Methilmill. It sat in the area between the water and what is now Poplar Road, Methil. There are no remains of the village today This stretch of the River Leven lies between two estates. On the west is the Wemyss Estate, owned by the Wemyss family, and on the east bank lies the Durie estate, owed by the Durie then Gilmour family. Both of these estates are very old, dating from the 12th and 13th centuries respectively.
  Until the late 19th. century, one of the principal populated areas of this stretch 
  of the river was at Kirkland, in the area next to the steel works, where over 
  800 people lived and worked. There are virtually no remains of the village or 
  the mansion, which once stood amongst the trees and was the home of the Peter 
  family, owners of the spinning mill that pre-dated the steelworks.
 Industry
  Milling, mining and fishing have always been the most prominent industries on 
  this stretch of the river. 
Mining 
  Records show that coal was mined from the banks of the river from as early as 
  1611 and probably much earlier. At Kirkland, several great water powered engines 
  were employed in pumping water from the pit back into the river. On the other 
  side of the river there were several small pits in the Durie estate. A lade 
  was dug in 18th century bringing water from Burnmill dam past the pit at Kirkland, 
  to power the water engines. It was later used to supply water to the spinning 
  mill, cyanide plant and steelworks, all of which occupied the site at various 
  times over the last two centuries. The lade has since been drained but the path 
  which it took is clearly visible today.
 Fishing
  Until the early 19th century, salmon fishing played an important part in the 
  local economy. The fish were caught at the mouth of the river Leven then shipped 
  to Perth or Newburgh for export to England. Pollution from the growing number 
  of mills on the river led to the rapid decline of the salmon population. 
 Spinning Mills
  In 1785 the 
  engines at the Kirkland pit gave way. Rather than repair them it was decided 
  that the site should be levelled and a spinning mill erected there. A Dundee 
  Spinning Company, Messrs. Neilson & Co. carried out the construction and operation 
  of the mill. Flax was mainly imported from Russia to the harbour at Methil for 
  use in the mill. All of the power for the handlooms in the mill came from the 
  river Leven. The mill produced damask, cotton, linen thread and sail cloth. 
  In 1810 the mill became the first in Scotland to be lit by gas. By 1836 the 
  mill employed well over 600 people in the preparation, spinning, bleaching and 
  weaving processes. Foreign competition in the 1880s led to the steady decline 
  of the spinning works at Kirkland. In 1889 the mill finally closed. 
 Other Industries
  In 1896 the site of the former spinning mill was bought and converted into - 
  of all things - a cyanide factory. Cyanide is an important part of the chemical 
  process used to extract gold from the ore. However, most of the world's gold 
  was being mined in South Africa and the Kirkland plant started operation in 
  the same year as the outbreak of the Boer war. Exports and prices dropped considerably, 
  leading to the speedy closure of the plant. 
Cameronbrig
  Before the distillery was established, the site had been used for grain milling 
  for several centuries. In 1822 John Haig visited the site and saw that the quality 
  of water and the proximity of grain farms and mills made the location ideal 
  for whisky manufacture. Field Marshall Alexander Douglas Haig, Commander-in-Chief 
  of British forces during WW1, was part of the Haig family and almost certainly 
  spent some of his childhood at Cameron House. In 1877 the distillery was taken 
  over by the Distillers Company in whose hands it remained until 1986 when it 
  was acquired by United Distillers. No whisky is made there today, only raw mash 
  which is used in the blending process. 
Creosote Works 
  When the creosote works first opened in 1887 it was sited on the Methil side 
  of the river, near Methil docks. As the docks became busier and grew the creosote 
  works moved across the river to their present site. Today they specialise, as 
  they have always done, in the treatment of telephone poles. 
Paper
   Most of the Leven's paper 
  mills are further upstream towards Leslie and Markinch. However, the town of 
  Leven had its own paper mill, the Millfield paper mill, which was established 
  in 1880. The mill is now closed.
 Railway 
  Around 1861 a mineral line was constructed from Cameronbridge (connecting with 
  the Thornton Leven line) to Methil docks. At Kirkland extensive marshalling 
  yards were constructed to help control the flow of railway traffic to Methil 
  docks. The line is still in use today carrying wagons full of coal for use at 
  Methil power station. The earliest remains of the once busy line is a handsome, 
  but dilapidated Victorian footbridge crossing the line at the old path to Mountfleurie. 
  
Sawmills
  Donaldsons have had a sawmill on the river Leven since 1890. They set up near 
  the newly built Methil docks to cut distribution costs, both in importing timber 
  and exporting it to the expanding Fife Coal fields. Since then they have expanded 
  the scale of the sawmill at Elm Park and have built a large roof truss plant 
  at Muiredge in Buckhaven. A venture into the DIY market saw the setting up of 
  a retail complex at Riverside Road Leven. The Riverside Road site was sold to 
  developers in the 1990's and now is a Sainsburies food Store, the DIY department 
  moving to Glenrothes.
Environment Pollution 
  The increasing number of mills which set up along the banks of the Leven during 
  the latter part of the 18th and most of the 19th centuries led to a steady increase 
  in the amount of pollution in the river. In 1874, the manager at Cameronbrig 
  was recorded as saying the smell from the river was so bad during the summer 
  that the whole distillery might have to close during the hottest months. The 
  main pollutants were caustic lye from the bleaching agents used by the spinning 
  mills and the water used to boil the rags in preparation for their being pulped 
  to make paper. Added to this was the sludge from the distillery at Cameronbrig, 
  waste from the steelworks at Kirkland and the considerable amount of sewage 
  from the growing villages and towns which grew upon the banks of the river and 
  its tributaries. 
By the end of the 19th century the water had become so polluted that it was deemed unusable by the mills around Leven and Kennoway. Despite efforts by the factories on the river to cut the waste being produced, by 1930 the River Leven and the River Ore were the most polluted rivers in Scotland. In 1956 a sewage pipe - known locally as the 'black pipe' - was built running parallel to the river carrying waste from the towns and villages upstream and discharging out to sea at Leven. This, coupled with modernisation of the factories on the river has considerably reduced the pollution levels in the river. However, the unauthorised dumping of domestic and - occasionally - industrial waste along the banks of the river has become a problem, despite the creation of a community-recycling centre at Kirkland and large scale landscaping projects.
 Landmarks 
  The large mound which sits between the river and the Windygates-Kennoway road 
  is known as Maiden Castle. Archaeological research shows that it was once the 
  site of a 12th century motte and bailey castle. It is believed locally that 
  Maiden Hill may have been an early Iron Age fort although no archaeological 
  evidence of this exists. However, the area and farm on the opposite side of 
  the river is known as Dunniface - cautiously translated as Fort of the Great 
  Worm. 
Bridges 
  Today there are many foot, road and rail bridges crossing the River Leven. The 
  oldest is Cameron Brig. This was once part of the main Kirkcaldy - Cupar road 
  which ran through the famous staging post at Cupar. Until the beginning of the19tht 
  century, Cameron Brig was also the only bridge across the river between there 
  and the mouth of the river. In 1821 a chain suspension bridge was built for 
  pedestrian traffic across the river at Leven on the site of an old ferry way 
  and ford. In 1840 it was replaced by a three-arched stone bridge with a toll 
  taken for crossing the bridge of one halfpenny (or a bawbee as they were known) 
  - hence the name Bawbee Brig. It is interesting to note that the toll keeper 
  - Davie Finlay - was the man once employed to ferry passengers across the river 
  in pre-bridge days. The present single-span bridge replaced the old stone bridge 
  in 1957. The footbridge at the bottom of Steelworks Brae was actually made from 
  the railway lines which once connected the steel works to the line across the 
  river. Other bridges that crossed the river along this short stretch include 
  the Iron Brig (road) and a rail bridge to Elm Park saw mill (dismantled), at 
  Donaldsons sawmills, a railway bridge at Methil Power station and a former railway 
  bridge at the steelworks, now used by lorries delivering to the creosote works.

  a dismantled rail bridge that once carried the mineral railway to Methil.
