Library of Celsus – Visitor Guide to Ephesus's Iconic Monument

The Library of Celsus is one of the most photographed and recognisable monuments in Ephesus—and indeed in the entire ancient Mediterranean. Built in the early 2nd century AD, it served as both a public library and a funerary monument (heroon) for Tiberius Julius Celsus Polemaeanus, a former Roman proconsul of Asia. With its ornate two-storey facade, four statues personifying virtues, and a collection of approximately 12,000 scrolls, it was the third-largest library in the Greco-Roman world, after those of Alexandria and Pergamum. Today, the reconstructed facade stands at the heart of Ephesus along Curetes Street, drawing millions of visitors each year. This comprehensive visitor guide covers the library's history, architecture, the four virtues, and practical tips for visiting in 2026.

History of the Library of Celsus

The library was commissioned around 114–117 AD by Tiberius Julius Aquila Polemaeanus, a Roman consul, as a memorial to his father Tiberius Julius Celsus Polemaeanus, who had died in 114 AD at the age of seventy. Celsus had been a member of the Roman Senate, consul in Rome in 92 AD (responsible for public buildings), and from 105 to 107 AD the proconsul of Asia—one of the most prestigious posts in the Roman Empire. He was also among the wealthiest businessmen in Ephesus. The library was a fitting memorial and burial place for such a prominent figure. Construction was completed around 117 AD, and Celsus was entombed in a lead coffin inside a marble sarcophagus decorated with high-relief figures of Nike, Eros, rosettes, and garlands. The sarcophagus was placed in a crypt beneath the library floor, near the apsidal wall. The library thus functioned as both a repository of knowledge and a mausoleum—a heroon honouring the deceased governor.

Architecture and Facade

The Library of Celsus stands at the corner of Curetes Street and the Marble Road (Arcadiane), at the very heart of ancient Ephesus, near the monumental Gate of Mazeus and Mithridates that opens onto the Commercial Agora. The surviving facade is 21 metres long and over 16 metres high. It rests on a nine-step podium and features two storeys, each with three pairs of columns capped with Corinthian capitals. The columns of the upper storey are shorter and slimmer than those below but support a central triangular pediment and two outer semicircular pediments. Between each pair of columns on the upper storey are large windows. The facade was cleverly designed to create an optical illusion: the podium is gently convex, and the side columns, capitals, and rafters are slightly smaller than those in the centre, making the building appear wider and more imposing than it actually is. The interior measured roughly 16.7 by 10.9 metres (about 180 square metres) and was paved with decorated marble. The walls were lined with niches for storing scrolls. A double-wall construction with a one-metre gap between inner and outer walls helped regulate temperature and humidity to protect the precious texts.

The Four Virtues – Sophia, Arete, Ennoia, Episteme

Four female statues occupy niches in the facade, personifying virtues associated with Celsus. From left to right, they represent: Sophia (Wisdom), Arete (Virtue or Goodness), Ennoia (Insight or Thought), and Episteme (Knowledge). The statues were inscribed with their names on the bases. The original statues were discovered during excavations and are now housed in the Ephesus Museum in Vienna; the figures you see in the niches today are faithful replicas. The facade is also richly decorated with relief carvings—including vegetation motifs and mythological scenes such as Bellerophon on Pegasus and depictions of Apollo and Dionysus—reflecting the fusion of Greek and Roman artistic traditions in Roman Asia.

The Library's Collection and Use

The library held approximately 12,000 scrolls of papyrus and parchment. Scrolls were stored in wall niches and were intended primarily for consultation on the spot rather than removal. Some borrowing may have been permitted for privileged readers. Tiberius Julius Aquila left 25,000 dinars in his will to purchase scrolls for the library. A large alcove inside once contained a statue—probably of Celsus or his son—which is now displayed at the Archaeological Museum of Istanbul. There was no full second floor inside, despite the facade's appearance; instead, a railed balcony ran around the interior at the second-storey level, giving access to higher niches.

Destruction, Restoration, and Later History

The library's interior and contents were destroyed around 262 AD, likely during a Gothic invasion or by earthquake. The facade survived, and repairs were made in the late 4th century; a small fountain was added next to the steps in front. In the 10th or 11th century, an earthquake caused the facade to collapse. The site was excavated in 1904, and the sarcophagus of Celsus was discovered. The Austrian Archaeological Institute reassembled and partially restored the facade between 1970 and 1978, using the original blocks where possible. The result is the impressive structure visitors see today—one of the best-preserved Roman library facades in the world.

Location and How to Visit

The Library of Celsus is located along Curetes Street, one of Ephesus's main thoroughfares, which connected the Lower Agora to the Upper Agora. It stands at the intersection with the Marble Road, near the Gate of Mazeus and Mithridates and the Commercial Agora. Visitors entering from the upper gate (Magnesia Gate) descend Curetes Street and encounter the library after passing the Temple of Hadrian and other monuments. Those entering from the lower gate reach it after walking up from the Great Theatre. The library is included in the standard Ephesus archaeological site ticket—no separate admission is required. Allow at least 20–30 minutes to appreciate the facade, read the informational panels, and take photographs. The library faces east, so morning light often provides the best conditions for photography.

Visitor Tips

• Visit early or late: The library is one of Ephesus's busiest spots; early morning or late afternoon visits avoid crowds and harsh midday sun.
• Photography: The facade is photogenic from multiple angles; try shots from the steps, from Curetes Street, and from the upper terrace.
• Combine with nearby sites: The Terrace Houses entrance is nearby; the Temple of Hadrian and the Great Theatre are within easy walking distance.
• Wear comfortable shoes: Curetes Street is paved with ancient marble—uneven and can be slippery.
