Auchenblae: Auchenblae (Scottish Gaelic: "Achadh nam Blàth" ) is a village in the Kincardine and Mearns area of Aberdeenshire, formerly in Kincardineshire, Scotland.  It is featured in Lewis Grassic Gibbon's novel, Sunset Song.  The name is a derivation from the Gaelic for "Field of Flowers" possibly due to the growing of flax in bygone times.  The village was known for its weavers, a whisky distillery and the annual Paldie's Fair horse market.  The current parish church, on the opposite side of the Luther Water was built next to an older chapel dedicated to St. Palladius and was formerly known as Fordoun Parish Church.  This location, known as at Kirkton of Fordoun was the birthplace of the chronicler John of Fordun (before 1360 – c. 1384) and has been a religious site since the 7th century.  St Palladius died and was reputedly buried here.  There is a Pictish cross slab, the Fordoun Stone, in the kirk's vestibule.  In the graveyard is the ancient ruin of St Palladius' Chapel and there is a memorial to Scotland's first Protestant martyr George Wishart, born at Mains of Pittarrow in the old parish of Fordoun and burnt at the stake under the orders of Cardinal Beaton in St Andrews.

St. Mungo's Parish Church: The church is named after St. Mungo (also known as St. Kentigern), patron saint and founder of the city of Glasgow.  It belongs to the Church of Scotland Presbytery of Stirling and serves the parish of Alloa.  A chapel dedicated to St. Mungo is thought to have been erected during the fourteenth or fifteenth-century, which became dependent upon the Parish of Tullibody.  Alloa had grown into a parish in its own right by 1600 when the Act of Assembly united the two parishes.  In 1680, the original chapel was rebuilt and enlarged.  The current church replaces the old parish church from the seventeenth-century which had been deemed much too small for the congregation for over seventy years and was declared ruinous and unsafe in August 1815.  The condition of the old church was so bad that services were often being held in the open air rather than risking injury to the congregation The decision was finally made to abandon the old building and find a site for a new parish church.  The Erskine family donated land at Bedford Place and work on the new St. Mungo's church began in 1817.  The church congregation temporarily worshipped in the Tabernacle until the completion in 1819 of the new church.  Since land was judged at the time to have too great a value to the living to be set aside for the dead, no graveyard was planned or added to the new church.  The more elaborate scale and design of the new building was intended to reflect the increased size and prosperity of the nineteenth-century congregation.  The church was one of the largest in Scotland at the time it was built.
