Schoolhouse #6
Why it's listed
Built in 1860 on Main Street in Guilderland Center, this one-room schoolhouse is made of coursed cobblestone with smooth ashlar quoins. Its 6/6 windows have stone lintels and sills, and an open bell tower with a curvilinear hipped roof rises at the southern end. A privy stood on the north side of the original school. Cobblestone construction is a traditional nineteenth-century technique indigenous to the northeast, but it is rare around Guilderland, and only several cobblestone buildings survive in Albany County. The schoolhouse is considered the best preserved cobblestone structure in the town. The Guilderland School District has maintained it carefully since construction, and it now serves as a storage building for the district. It sits on about 1.3 acres amid a modern suburban community, beside St. Mark's church on the west and houses on the east. It was recognized for its architectural value as a distinctive local example of the cobblestone building tradition.
Significance in brief: It is one of only several cobblestone buildings in the county and the best preserved cobblestone structure in the town. It is a well-executed example of a nineteenth-century construction technique native to the northeast but rare in this area. The form recommends it under Criterion C.

What listing means for this property
For a publicly owned building or structure, listing mainly matters when federal funds, permits or licences are involved: projects then go through Section 106 review so effects on the property are considered. Listing also strengthens applications for preservation grants and, for leased income-producing uses, can enable the federal rehabilitation tax credit.
