Geography Woldingham is a village and civil parish in Surrey; its buildings lie at 150–248m AOD within the M25, south-by-southeast of London. Situated high on the North Downs in its Area of Outstanding Natural Beauty between Oxted and Warlingham, a straight line to Oxted measures to the southeast, the Tandridge's administrative town. Woldingham is home to one of the smallest churches in the country – St. Agatha's (it only seats 40 but it served as Parish Church of Woldingham until 1934 and is still in regular use). First mentioned in 1270, St. Agatha's is the county's smallest church with dimensions of 30 ft 3 in by 20 ft 2 in (9.2 by 6.1 m), and at 797 ft (243 m) above sea level is the third highest old parish church in Surrey. Elevations Buildings lie at 150–248m AOD; the lowest point is at the Croydon Road roundabout at the foot of Woldingham Road, which is 106m AOD; the highest point is along The Ridge, a road which is parallel to the North Downs Way, which is 261m AOD and is a continuation of the highest point of the North Downs, Botley Hill, higher. From the nearby areas of high ground impressive views can be enjoyed – and from some places one can see much of Greater London as far as the Chilterns, or looking south the Vale of Holmesdale, Greensand Ridge and woods of the Weald. An impressive view over Oxted and The Weald from the North Downs Way above the works of lime quarries reflects the geology of the North Downs, with rolling or very gradual north slopes and a steep south slope. Soil and geology Relatively wide bands of chalky soil intersperse the brick-earth topping of the downs, all of which is relatively quick draining making some agriculture challenging. A majority of this Downs-topping soil is free-draining, slightly acid, loamy soil beside this free-draining, lime-rich, loamy soil, i.e. alkaline.
