The Hasmonean and Herodian Palaces at Jericho
The Hasmonean and Herodian royal winter palaces, located at Tulul Abu el-‘Alayiq near the entrance of Wadi Qelt, represent a remarkable archaeological complex from the Second Temple period. Situated in the Jericho valley, these palaces showcase the opulence of the Hasmonean dynasty and Herod the Great through their luxurious architecture and advanced infrastructure.
Historical Context and Discovery
The Hasmonean and Herodian palaces served as royal winter retreats, offering proximity to Jerusalem—approximately 20 kilometers along the Roman “Ascent of Adummim” road. They were designed to take full advantage of Jericho’s warm climate and abundant water sources, supplied through aqueducts from nearby springs.
Excavation History
- Initial Exploration: British archeologist Sir Charles Warren’s 19th-century excavation identified the site as Roman-era due to its architecture.
- Further Investigations: In the early 20th century, German archaeologists Ernst Sellin and Carl Watzinger conducted research, although their findings remained unpublished.
- Modern Excavations: Ehud Netzer’s extensive ten-season excavation from 1973 revealed a detailed understanding of the Hasmonean and Herodian structures, including aqueduct systems and synagogues, making this one of the richest archaeological sites from the Second Temple period.

Destruction and Preservation
A major earthquake in 31 BCE devastated the Hasmonean palace, preserving many features under layers of rubble. Herod the Great subsequently incorporated its remains into his new palaces.

The Role of Water Infrastructure
Aqueducts from nearby springs such as Ein Qelt and Ein Duyuk were instrumental in sustaining the palaces and surrounding estates. These systems supported:
The fertile soil and abundant water allowed cultivation of valuable crops like dates and balsam, used for perfumes and medicines.
Pools and fountains were key to the luxurious ambiance of the palaces.
