1 Rial - Qaboos Matrah Fort

Issued by the Central Bank of Oman as part of a broader commemorative program documenting Oman's historic fortifications, this piece belongs to a series that accelerated significantly through the 1990s as the sultanate invested heavily in restoring and cataloging its Portuguese-era and pre-colonial defensive architecture. Matrah Fort, overlooking the old port district of Muscat, dates to at least the sixteenth century and remained an active military installation well into the twentieth — the Omani government only transferred administrative control of such sites to heritage authorities following substantial political stabilization after the 1970 coup that brought Qaboos to power.
