Trinity Hall
The opening of Trinity Hall in 1959 marked the advent of a “new Delbarton”. Prior to Trinity Hall, Old Main (the former Kountze family summer seat) had been “Old Everything” at Delbarton. With the completion of Trinity Hall, designed as Delbarton’s first true instructional center, the School truly came of age. The spacious new building accommodated all classrooms, science labs, the Valentine Library and most administrative offices. In 2009 we celebrated the 50th Anniversary of Trinity Hall and, today, Trinity Hall remains Delbarton’s main learning center.
