Sampaloc is a district of Manila, Philippines. It is referred to as the University Belt or simply called "U-Belt" for numerous colleges and universities are found within the district such as the University of Santo Tomas, the oldest extant university in Asia; the National University, the first private nonsectarian and coeducational institution in the Philippines; the Far Eastern University, known for its Art Deco campus and cultural heritage site of the Philippines; and the University of the East, once dubbed as the largest university in Asia in terms of enrollment. The district is bordered by the districts of Quiapo and San Miguel in the south, Santa Mesa district in the south and east, Santa Cruz district in the west and north, and Quezon City in the northeast.
Aside from being the "University Belt", Sampaloc is also known to Metro Manila and the surrounding provinces for its Dangwa flower market, located in Dimasalang Road, well known as the selling center for cut flowers from all over the Philippines, mainly Baguio. Sampaloc is also the location of a former colonial mansion, now called Windsor Inn, which is popular among backpackers and budget travelers.
Barangays 395 to 636 of the City of Manila would all have belonged to Sampaloc and comprise 241 barangays for the district.Final Results - 2007 Census of Population However, what are now known as barangays 587-636 became part of Santa Mesa when these areas were separated from Sampaloc after Santa Mesa became a separate parish in 1911. Santa Mesa is now a part of the 6th congressional district of Manila, while Sampaloc is the sole district comprising the 4th congressional district of Manila.
Many streets in Sampaloc, particularly in the northeast portion divided by España and Lacson Avenues and also street names in neighboring Quezon City, have names that are directly associated with the Philippine national hero José Rizal, either named after the places (e.g. Calamba, Dapitan), real-life people (e.g. Blumentritt), characters from his novels (e.g. Ibarra, Maria Clara) or his pen names (e.g. Laong Laan, Dimasalang).
It is also known as the birthplace of Benigno Aquino III, the 15th President of the Philippines.
Etymology "Sampaloc" or "Sampalok" is the native Tagalog word for the tamarind fruit; the place was likely named after tamarind trees that may have been prevalent in the area.
History
The founding of Sampaloc as a town coincided with its establishment as a parish independent of Santa Ana de Sapa in 1613. At the time, it included what is now Pandacan which was separated from it in 1712. Sampaloc would comprise ten barangays ― Bacood, Balic-Balic, Bilarang Hipon, Calubcub, Manggahan, Nagtahan, San Isidro, San Roque, Santa Mesa, and Santol.
Outbreak of the Philippine-American War
Following the Philippine Revolution against Spain and the Treaty of Paris of 1898 which seceded the Philippines to the United States, the subsequent arrival of American colonial troops shortly drew animosity between both American troops and Filipino troops.
On the evening of February 4, 1899, Private William W. Grayson fired the first shot of the Philippine-American War at the corner of Sociego Street and Tomas Arguelles Street. A study done by Ronnie Miravite Casalmir places the event at this corner, not at Sociego-Silencio where they erroneously have the marker. The Ronnie Miravite Casalmir Study debunks the previous findings of Dr. Benito Legarda which was the basis for the erroneous placement of the marker at Sociego-Silencio. According to Ronnie Miravite Casalmir, the smoking gun for the Sociego-Arguelles corner is the presence of Blockhouse 7 in the background of Grayson's reenactment photo. The orientation of this Blockhouse 7 image lines up with the corner of Sociego and Arguelles when compared with the known photo of Blockhouse 7 taken from the same direction. In addition, the distance estimate of Lieut. Whedon placed the 100-yard distance from Santol at Sociego-Arguelles, not Sociego-Silencio. This meant that when Lieut. Whedon ordered the detachment at Santol to patrol 100 yards, he meant them to patrol all the way to Sociego-Arguelles. Col. Stotsenburg corroborated Lieut. Whedon's distance estimate. Prof. Ambeth R. Ocampo calls the evidence presented by Ronnie Miravite Casalmir as new and compelling. Prof. Ocampo agrees that this evidence shows that the marker should be moved one block away, from Sociego-Silencio to Sociego-Arguelles. Maj. Lillian A. Pfluke (Ret.), West Point Class of 1980, and founder of the American War Memorials Overseas Inc. also agrees and has a note on their U.S. War Memorials website that the proper placement of the marker should be at the adjoining intersection of Sociego Street and Arguelles Street where the incident actually occurred.
American colonial era In 1901, with the chartering of the city of Manila under the American-led Taft Commission, where most of Sampaloc, with the exception of barangay Bilarang Hipon, would be absorbed by the city of Manila when its borders were extended outside the walled city now known as Intramuros. The latter barangay would be incorporated into San Francisco del Monte town and later on Quezon City, being divided later into several villages itself under what is now its 4th district.
In 1911, Santa Mesa became a separate religious district (parish) out of Sampaloc when the first and oldest parish in the Philippines in honor of its Titular Patron, the Sacred Heart of Jesus, was established. However, it remained politically part of Sampaloc.
Contemporary period
In 1996, Ramon Bagatsing Jr., the then-representative of Manila's 4th district, launched a program called the "Sampaloc Experiment", which sought to implement the then-new subject of computer education within the district's public schools as a trial program for the rest of the country.
In the afternoon of April 28, 2025, chairman Leninsky Bacud of the Ang Bumbero ng Pilipinas partylist (ABP, ) was assassinated by two motorcycle-riding gunmen while he was standing just outside the covered gym of Barangay 435, of which Bacud was a former barangay captain. Even after Bacud was shot, witnesses recounted that the backrider stepped off the motorcycle and continued firing multiple shots at Bacud on the ground even as he was pleading for his life. Bacud had been running as the partylist's second nominee in the 2025 elections at the time of the shooting.
