[3] Passi is the only component city in the province of Iloilo, and ranks as the largest in terms of land area and income, and second only to Oton in population size.

Construction was completed during Padre Pedro Ceberio's tenure, with Salvador “Badong” Panes Perfecto serving as the town's Captain at the time.

[6] Passi experienced significant development during this period, becoming a center for trade and commerce due to its strategic location.

According to popular legend, Spanish conquistadors stumbled on a small hut by the river's bank where an old woman was found winnowing pounded rice.

Misinterpreting the question, the woman responded with "Ah, pasi," which in her language meant "rice", assuming they were asking about the contents of her basket.

An alternative interpretation is that "pasi" was a local Malay dialect from the word 'putih' which means "white" - possibly referring to the encounter with the Spaniards themselves.

Its terrain is predominantly flat, extending along the Jalaur and Lamunan Rivers, with mountainous regions situated in the northern part of the city.

Passi, akin to many inland areas in Iloilo, lacks a distinct rainy season or pronounced maximum rainfall period.

Additionally, other Christian sects present in Passi City include the Iglesia ni Cristo, Church of Christ (Latter Day Saints), and Jehovah's Witnesses.

The city's economy relies heavily on agriculture, with a diverse range of crops including rice, corn, vegetables, coconut, sugarcane, and pineapple.

Notably, Passi has been a major pineapple producer for years and has also been recognized for its involvement in other industries such as fruit processing, wallboard production, metalworking, and cut-flower propagation.

Locally made products like pineapple wine, jam, and fruit preserves have gained recognition through participation in various trade fairs and exhibitions, including the annual Fiesta in the City celebration in May, Tumandok in September, and Wow Philippines: the Best of the Region.

Passi possesses favorable physical resources, including fertile soil along rolling hills and narrow valley plains, abundant surface and groundwater, and a climate without distinct dry and wet seasons.

Industrial development is a key focus area for the local government, given Passi's designation as one of the five Agro-Industrial districts in the province.

[citation needed] As a component city of Iloilo Province, Passi serves as a significant shopping destination outside the provincial capital.

One of its notable programs is Talking Point, where individuals or organizations are interviewed on topics relevant to Passi City.

[clarification needed] Attractions in Passi encompass a variety of sites, including extensive pineapple plantations, cock farms, the Baroque Church of Saint William the Hermit, the historic Muscovado Chimney, the Chameleon Butterfly Garden, the Amorotic caves of Barangay Magdungao, scenic highway vistas offering captivating sunset views, and the aging Railway Bridge spanning the Jalaur River.

[citation needed] Passi celebrates the feast of its patron saint, San Guillermo de Ermita (St. William the Hermit), on February 10, accompanied by the coronation of the fiesta queen.

Typical of churches from this era, one can observe the Augustinian seal on the archway over one of the side entrances, suggesting their involvement in its construction.

The church remained intact through the Revolution and the Philippines American War, but in 1932, it suffered damage when its roof was blown away by a typhoon.

[23] The complex will feature a rubberized oval, an improved grandstand, perimeter fencing, and provisions for a future Olympic-sized swimming pool.

The Passi City Gymnasium, inaugurated in May 2018, has hosted exhibition games featuring teams from UAAP and PBA.
