When originally built on the hillside in 1892, Duluth Central High School was famed not only for its grand clock tower, which could be seen for miles, but also for its wide halls, sweeping stairways with iron banisters, large chandeliers, and beautiful statuary.

Due to age and safety conditions, the Duluth School Board decided in 1970 that it would have to build a new school to replace the Historic Old Central High School. In 1971, the new Central High School building was built on top of the hill and the school moved there, leaving School District administrative offices in the old building.

In 2007, the Duluth School Board announced that they would support the long-range Red plan for the district which would close Duluth Central and keep a renovated Ordean Middle School (now Duluth East High School) and Duluth Denfeld High School as the only two high schools in Duluth.

2011 was the last graduating class of Duluth Central High School. The grounds and the buildings would remain empty until sold by the school district.

In November 2013 the Duluth City Council met to finalize plans to rezone the land from an R-1 (residential zone) to a commercial C zone paving the way for ISD 709 to sell Central High School to potential land developers for commercial purposes. In December 2014, the sale of the property was announced. 46°47′21″N 92°06′00″W / 46.7891063°N 92.0999118°W / 46.7891063; -92.0999118

It was announced on August 8, 2022, that Chester Creek View LLC purchased the majority of the property, including the school building. Demolition of the building began on November 14, 2022.

In February 2024, the Duluth City Council voted in support of a $500 million redevelopment plan. It would include 1,300 housing units and commercial space. The developer is Lazar Ostreicher.

Big red was given to Duluth Central High School [teams] until 1930. In that year, students decided to change the name to the "Trojans". This was done through a contest in which all students could participate. The Trojan has been the symbol and name for Central [teams] ever since.

Central claimed numerous Minnesota State High School League state championships, with most of them coming in basketball, skiing, and ski jumping.
