Ulpian Library, Ancient Roman library in Forum of Trajan, Italy.
The Ulpian Library was a public library building in Trajan's Forum in Rome, built with two floors where scrolls and books were stored in wall niches. High windows along the upper level let daylight into the reading areas, while the thick walls helped protect the stored materials.
The library opened shortly after the dedication of Trajan's Forum in 113 CE, as part of one of the largest building projects Rome had ever seen. Over the late Roman period it gradually lost its original function and was eventually absorbed into later structures.
The building held not only literary works but also the Acta Senatus, the official records of the Roman Senate. This gave the library a role that went beyond reading, making it a place where the memory of Roman public life was kept.
Only scattered remains of the building survive today, and they are part of the broader Trajan's Forum archaeological area in central Rome. Walking around the whole forum site helps make sense of where the library stood in relation to Trajan's Column and the Basilica Ulpia.
The library was in fact a double building, with two separate structures facing each other on either side of Trajan's Column, one for Greek works and one for Latin works. This split shows how naturally Romans treated Greek culture as a parallel tradition alongside their own.
