Located in front of the Paterno House, the immense Zamora House forms part of the only surviving cluster of heritage houses along with the once-grand Calle Hidalgo.
The house was home to Manuel A. Zamora, a chemist and pharmacist who invented the tiki-tiki formula to combat beriberi, a severe and chronic form of thiamine (vitamin B1) deficiency.
His invention helped reduce infant mortality in the Philippines.
The house, built in the 19th century, is in relatively good condition. However, there are plans to redevelop the property.
One of Quiapo’s greatest treasures is its collection of heritage houses that date from the 19th and 20th centuries. Quiapo east of Quezon Avenue was largely spared from the destruction of the Battle of Manila, thus providing a rare glimpse into Manila’s old architecture. Sadly, this treasure is underappreciated and largely endangered due to postwar “development” and lack of state support and regulation which has led to the demolition of many heritage houses and heritage structures in the city.
