It is the largest of three public parks in Makati's old downtown area situated at the site of the Casa Hacienda, a former plantation house.

Poblacion Park features an amphitheater, children's playground, stone benches, gazeboes, multipurpose sheds and solar lamp posts.

A 75-meter (246 ft) extension of the park eastwards to Rockwell Center was inaugurated in June 2016 by the then-acting Mayor Romulo Peña.

It was the site of a large bahay na bato that served as an administrative building for the then vast Jesuit hacienda of San Pedro de Macati.

[7] The Zobel de Ayala family managed their estate here from their headquarters at the casa hacienda until post-independence when the house was demolished and the site turned into an open space.
