Ongkharak

Ongkharak is an administrative district in Nakhon Nayok Province consisting of eleven sub-districts and 116 villages overseen by a central office. The administrative headquarters sits near the Saovabha Market complex and coordinates services across the area.

The administrative office relocated in 1889 when King Chulalongkorn initiated the construction of Rangsit Canal to improve water management in the region. This canal project reshaped the district's geography and infrastructure.

The name Ongkharak comes from a memorial to royal guards, showing how the district connects to Thailand's monarchy through its naming. This origin shapes how locals understand their area's place in the broader kingdom.

The district operates through eleven local administrative organizations that handle services and infrastructure projects for residents. Visitors and residents can access local services through these decentralized offices spread across the area.

Srinakharinwirot University sits about four meters above sea level in Ongkharak, positioned between two major waterways. This location between the Nakhon Nayok River and Khlong Rangsit connects the campus to the district's water management history.
