The Marshalland Spring exits the bedrock of the underlying limestone strata within Spier's Old School Grounds close to the Geilsland Road. The site was once in a field of the old Marshalland Farm that eventually became Spier's School.
The Marshalland Spring is the ultimate source of the Marshalland Burn and once outside the Spier's parklands it runs through a culvert until flowing into the open beside Marshalland Playing Fields and finally flowing down past Craig House to join the Powgree Burn near Brigghouse.
Other springs rise within the Spier's grounds and one was probably the source of the water for the old carbonated water factory that once existed at Bellscauseway. During WW2 Polish prisoners of war preferred water from this spring to their own supply at their camp near the DM Beith site.
A pond existed at the Marshalland Spring in the days of the school and the site has always been ideal for frogs and toads. In 2012 work started on digging out the old pond and on building a 'well feature' where the spring emerges from the bedrock.
