Hanes Field, named after John Wesley Hanes, who started the Hanes Hosiery Company in Winston-Salem in 1901, was the primary athletic field for both baseball and football at Trinity College - it appears to have been built in the mid-1910s.was a well-regarded facility - so much so that it was used for spring training by Boston in 1899, by the Durham Bulls upon the re-establishment of their club in 1913, and by the Trinity College Roosters.

Built in 1902 with a donation of funds from Mrs. Mary Lyon Stagg, a daughter of Mary Elizabeth Duke Lyon, who was a sister of James and Benjamin Duke, the Stagg Pavilion bears a resemblance to the Rotary Park pavilion, built in 1916, and now located at Bennett Place

Built as a residence for Methodist Bishop and former Trinity College President John Kilgo, the Bishop's House later became a Faculty Club, and during the mid-20th century served as the infirmary. It currently serves as the center for Continuing Education at Duke.

The Anne Roney Fountain originally was situated in a prominent position directly in front of the Old Main / Washington Duke Building. Roney was the sister of Artelia Roney, Washington Duke's second wife. Anne helped Duke raise his children after Artelia died, and was housekeeper at Fairview, his house on the southeast corner of South Duke St. and West Main St..

There is little to no information available about the Edwards/Robertson house. It is labelled as "Prof Edwards" house on the 1902 map above, and as "Robertson House" on the 1937 and 1950 Sanborn maps.

Little information is available regarding the President's House, or what function it served after the construction of the President's house at the entry to Duke's West Campus in the 1920s. It was likely designed by CC Hook and built contemporaneously with the Flowers House.

Robert Flowers was one of a handful of faculty who moved with Trinity College from Trinity to Durham, teaching electrical engineering and mathematics. Demonstrating the all-hands-on-deck mentality of a Naval Academy graduate, Flowers wired the new Durham campus for electricity himself. In the first decade of the 20th century, he built a house on campus, designed by CC Hook.

North Dormitory was built in 1902 to expand housing for male undergraduates. It was called North Dormitory until 1912, when it was renamed Alspaugh in honor of Colonel Alspaugh, at the time the oldest living alumnus of Trinity College (1855) and evidently a large financial contributor to the college.

In 1900, James B. Duke donated funds for a library building. The building was designed to hold 100,000 volumes. The formal opening took place in February 1903. The college's library holdings numbered 15,000 volumes; Duke donated an additional $10,000 to purchase books for the library.

Craven Memorial Hall was part of the significant expansion of Trinity College that took place around the turn of the century. Prior to its construction, chapel services had been held in the College Inn. Craven was used for performances and commencement as well - thus its more generic name, but it is labelled in a 1910s Trinity Annual as simply "Chapel."
