Beyond the famous travertines and ancient theatre, Hierapolis holds lesser-known sites that reward curious visitors.

This guide covers what to see and how to secure your tickets in advance.
Hidden Gems in Hierapolis: What to See
While most visitors head straight for the theatre and travertines, these sites offer a deeper glimpse into ancient Roman and Byzantine life. All are part of the main archaeological zone and require no extra ticket.
1. The Plutonium (Pluto's Gate)
Near the Temple of Apollo, the Plutonium was a sacred cave sanctuary dedicated to Pluto (Hades), the god of the underworld. The cave emits toxic gases from an underground hot spring—ancient sources describe how animals brought near would perish. The ancients believed these vapors were "Pluto's breath." Today the site is fenced for safety, but you can view it from a distance. It remains one of Hierapolis's most mysterious attractions.
2. Frontinus Gate (Domitian Gate)
On the north side of Hierapolis, the Frontinus Gate is the best-preserved gate in the city. Built by Julius Frontinus, proconsul of Asia Minor (84–86 CE), it was dedicated to Emperor Domitian. The gate features two round towers and three openings. One tower remains in excellent condition. It marks the northern entrance to the ancient city and is often overlooked by visitors rushing to the theatre.
3. Martyrium of St Philip
An extraordinary octagonal structure built on the site where Saint Philip, one of Christ's twelve apostles, was martyred around 80 CE. The monument dates to the 5th century and features eight individual chapels marked with crosses. It served religious ceremonial purposes. In 2011, archaeologists discovered what is believed to be St. Philip's remains in a nearby Byzantine structure. The Martyrium sits on a hill northeast of the main ruins—allow extra time to reach it.
4. The Ancient Latrine
Hierapolis contains a remarkably well-preserved public latrine. The building has an elongated plan with two side entrances, constructed from travertine blocks. A waste-water channel on the floor connected to underground sewers. Despite earthquake damage over the centuries, the structure survives with its main features intact. It offers a rare glimpse into Roman urban infrastructure.
5. The Agora
One of the largest agoras ever discovered, dating to the 2nd century. It was surrounded by marble porticoes with Ionic columns on three sides and enclosed by a basilica on the fourth. The agora was the commercial and social heart of the city. Today the foundations and column bases give a sense of its scale.
6. Byzantine Gate and Early Christian Structures
A 5th-century Byzantine gate, built of travertine blocks and marble, marks one entrance to the site. Hierapolis flourished as a Christian center in late antiquity. Several early churches and chapels survive, often overshadowed by the more famous Roman ruins.

Visitor Tips for Exploring Hidden Gems
- Allow extra time—these sites are spread across the plateau; rushing means you might miss them
- Stay on designated paths—do not climb on ruins or enter fenced areas (e.g., Plutonium)
- Bring water and sunscreen—shade is limited between sites
- Wear comfortable shoes—uneven terrain and marble paths
- Combine with main attractions—see the theatre and travertines on the same visit
