Records indicate that the Triangle School was built in the Town  of Hortonia in late 1857.  At that time the towns of Hortonia, Dale, Caledonia and Mukwa compromised common school district no. 3.  There were two schools then, one in Hortonia and the other at Young's Corner (Medina).  The school was built of brick, which came from a brickyard that was located in Hortonia.  (Wood siding now covers the school).  On October 10, 1874, William Zuelke and his wife, Emma, sold land the school was located on to Henry Rushman, but there was no stipulation about the schoo.  At this time, the school was called 'Elms School' because of the small elm trees planted around it.  There was no well at the school, so water had to be fetched from a fountain on the Rushman property.  Sometime between 1930 and 1935, a road curve was put in at the intersection of Hwy. 45, Ledgehll and Cross Roads, which explains the name change to Triangle School

The last class graduated in 1948.  Students were transferred to the New London School district.  The New London District purchased the school desks and books, and took over the records.  The school was idle until 1954 when the New London Board of Education held a public sale.  Mrs. E.H. Jack, Route 3, New London, purchased it to be used for storage space.

In 1977 a small group of New London residents started the New London Historical Society and decided to buy the school from Mrs. Jack.  After the purchase, the Rushmans donated another acre of land adjacent to the building.  After three years of renovation, the completely restored 1857 school was opened to the public.  A new roof was put on the school and woodshed in 1985.  The school was moved to the Village in 1990.

The school still contains many of the original furnishings and school pieces including a sand table, clock and water cooler.  The original weather vane and mannequins clothed in vintage attire give you the complete feeling that you have just stepped back in time for a day at school.
