*Schedule:

   (disused)

*Remarks:

   Original bells cast in 1950; original
   keyboard had space for addition of 7
   notes; 10-note chiming drum.
   Various repairs in 1977, 1982.
   Tower renamed in 1997, on centennial
   of the death of Andres Bonifacio.
   2007: After a silence of 18 years,
   this carillon was replaced with a new
   instrument; the old bells have been
   retired, but some may be re-used
   elsewhere.  New keyboard appears to
   have space for addition of an octave
   of trebles.  Also a MIDI keyboard for
   autoplay recording.

The Website of the carillon restoration project has full details, including clickable photos of the deplorable condition of the instrument before restoration.  (The original plan, to retune the existing bells, was not carried out.)

Blogger's photo of the base of the tower during turnover ceremonies

A Weblog page on the rededication of the carillon includes two clickable pictures of the tower.

On a photographer's page, the third picture is the U.P. Carillon Bell Tower at night.

A TV news clip (in Filipino?) about the new bells includes keyboard photos.

Photo of six of the Vanbergen bells after removal from the tower

In a video photo album of the tower, the first portion (4:25) shows photos of the tower with the original bells in their frame (and its truly dreadful condition), but the audio track appears to be orchestral tubular chimes and percussion.  The last minute of that video shows the new bells in the frame, lower in belfry (but repeats the same audio track).  Another version of the same video (4:39) is a few seconds longer, possibly with some additional photos included.

A blogger's photo of the tower top (minus bells?)

Photo of the top of the tower, showing bells in place (presumably the new ones)

Local page with three photos of the old bells and the tower, all clickable for large and huge versions.
The same photographer posted elsewhere a better version of the photo of three Vanbergen bells after removal from the tower.

A blogger's page about climbing the tower of UP Diliman turns into a slideshow (with the right browser); the 36 photos include the manual keyboard (with space to add a treble octave), P&F nameplate, belfry access, bells in frame, etc.

A 2019 article on the carillon has photos of the the tower and the baton keyboard and in the belfry.

A simple version of the campus map shows the location of the carillon tower.
