This striking red 10 centavos stamp was issued in 1917 during the period when the Philippine Islands were under U.S. administration. It depicts Fort Santiago, the historic citadel located in Intramuros, Manila, originally built by the Spanish in the late 16th century. The fort played a vital role in Philippine history, serving as a military defense structure and later as a prison. The stamp is framed with stars along the border and inscribed with “United States of America – Philippine Islands.”

Highly collectible, this issue represents the Philippines–U.S. colonial postal history and is part of the series showcasing significant landmarks of the islands. Its bold red engraving, combined with the cultural and historical importance of Fort Santiago, makes it a standout piece in early 20th-century Philippine philately.
