Source-derived summary

The 1910 Fort Bonifacio War Memorial Tunnel is a tunnel that was part of Fort William McKinley (renamed Fort Bonifacio), a military base built by the US Military Government of the Philippines in 1902. The tunnel alignment is now part of Taguig's Bonifacio Global City district and the Embo barangays, and is considered a historical site by the Bases Conversion Development Authority (BCDA). The main roads near it are C-5 and Kalayaan Avenue.

History

The tunnel was initially used as a passageway for military supplies and war materials. It was first constructed around 1936 with

the help of Igorots. It stretches 2.24 kilometres (1.39 mi) at an average depth of 70 feet (21 m) that spans from the Pasig River, to the area now called Pembo and East Rembo.

The Fort McKinley Tunnel was intended for the creation of an underground aerial bombing-free Air Warning Service of the Army Air Force known as “The Fort McKinley Project”. It was to be a part of the modernization of the country's communication facilities. Digging for the tunnel began in October 1941.

On January 2, 1942, the Japanese entered Manila.

Editorial analysis

Why this record matters

“Fort Bonifacio Tunnel” is worth following because a concise public description often conceals a longer documentary argument. Here, Fort, Bonifacio and Tunnel provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q17070576. Authority coordinates are 14.545, 121.061. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
