Two sites define Kermanshah's claim on deep history. Bisotun, inscribed as a UNESCO World Heritage Site, features a massive rock relief commissioned by Darius the Great around 520 BCE. Carved high into a limestone cliff, the trilingual inscription -- in Old Persian, Elamite, and Babylonian -- records Darius's rise to power and proved essential to deciphering cuneiform script in the 19th century. It was, in effect, the Rosetta Stone of Mesopotamian writing. Thirty kilometers from the city center, Taq-e Bostan offers a different kind of grandeur: Sasanian-era rock carvings depicting royal investitures and elaborate hunting scenes set within arched alcoves. Water still flows from a natural spring at the base of the cliff, pooling beneath reliefs that have watched this valley for over 1,600 years.

Kermanshah Province hides as much underground as it displays above. Prav Cave, located in the mountains between Taq-e Bostan and Bisotun, plunges to extreme depths and contains glaciers and a 762-meter-deep valley threaded with underground streams. Quri Qaleh cave, 92 kilometers toward Paveh, stretches 12 kilometers along its length, with a spine of 3,140 meters and an underground river flowing at 111 liters per second. Inside, chambers are hung with icicle-like formations and colorful mineral columns, lit by the kind of geological patience that makes human timescales feel brief. The Zagros Paleolithic Museum in Kermanshah -- the first museum in Iran devoted entirely to the Paleolithic period -- displays stone tools and animal fossil bones excavated from these caves and others, artifacts from a time when this region's inhabitants were shaping flint rather than empires.

Talab-e Hashilan, a 1,500-hectare marsh 32 kilometers from the city, contains something genuinely strange: tiny floating islands. These natural platforms of matted vegetation drift across the wetland's surface, sheltering roughly 200 species of birds among their plant cover. The marsh sits in a mountain depression where springs feed a shallow lake system, creating an ecosystem that feels transplanted from somewhere far gentler. It is the kind of place that challenges assumptions about what the Zagros landscape can produce. Beyond the marsh, the mountains offer their own variety -- alpine meadows, oak forests, deep gorges -- all within reach of a city that still functions as a busy regional hub.

Kermanshah is a Kurdish-speaking city where cultural identity lives in the tangible. Giveh, the handwoven cotton shoe traditional to the mountainous regions of western Iran, is still produced here and in nearby Paveh and Harsin. The shoe's upper is woven from thread -- once wool or cotton, now often synthetic -- while the sole was historically cut from wild-bull leather before rubber became available. In the old bazaar, Kermanshahi butter, nan-e berenji (rice cookies), and nan-e roughani (oil bread) crowd the stalls alongside gilim flatweave rugs and local clothing. The Tekyeh Moavenalmolk houses an ethnography museum in a Qajar-period building, its mirrored walls and painted tiles reflecting a city that has always valued the decorative arts. Four museums occupy old Qajar houses across the city, preserving calligraphy, epigraphy, and traditional martial arts -- a wrestling museum filled with wax figures of pahlavans, the strongmen of Persian tradition.
