 The Tudor Gothic building which housed the school was undermined , in 1892 , by the construction of the Baltimore & Ohio Railroad tunnel from Camden Street Station to Mount Royal Station and collapsed . In 1895 , a new larger structure , designed in the Romanesque Revival style by the noted local architects Baldwin & Pennington , was erected on the same site , only facing the Centre Street northern side . This new building quickly became overcrowded and an annex was established on 26th Street . The addition did not help with the increase in school @-@ aged youth beginning to attend City College by World War I. During the 1920s , alumni began a campaign to provide the school with a more suitable building , and , in 1926 , ground was broken for a massive Collegiate Gothic stone castle on Collegian Hill at 33rd Street and The Alameda . This new structure cost almost $ 3 million and officially opened April 10 , 1928 .
