Miagos or Osmoxylon lineare is a flowering plant from the family Araliaceae that used to grow abundantly in the area when the Spaniards came.

Because of its abundance in the area, the Spaniards named the place Miagos which later became Miagao.

[7] A settlement in Damilisan were recorded by Spanish Map early in 1700 with 13,493 people and 2,974 houses.

Most of the flat areas in the municipality are found either in coasts or along the town's major rivers which include the Naulid, Tumagbok, Oyaoy, Bacauan, Tabunacan, Oyungan, Lanutan, and San Rafael rivers.

A mountain range forms a natural boundary between Miagao and the province of Antique to the north.

[10] The highest point in the municipality is the summit of Mount Tulajon, locally spelled as Tulahong, at 1,100 meters asl located in Barangay Ongyod.

[21] The main components of the Municipal Health Office include the following: There are also other private medical, dental and veterinary clinics, laboratories, and pharmacies located primarily in the poblacion area.

Buses that ply the Iloilo-Antique, Iloilo-Caticlan via San Jose, and Iloilo-Manila routes pass by the municipality every day.

Ceres Liner by Vallacar Transit passes by Miagao almost every 30 minutes on its way to Iloilo from Antique and vice versa.

In addition, RM Liner also heads to Manila everyday but passes by Miagao early in the evening.

Several mountain barangays of Miagao are also served by jeepneys because smaller modes of transportation aren't usually strong enough to climb steep and unpaved roads.

Tricycles are often limited to operate within the municipality but special and private trips to other places are allowed.

On the front facade, which is flanked by two watchtower belfries, one can see the unique blending of Spanish and native influences.

The central feature of the bas-relief facade is a large coconut tree which reaches almost to the apex.

While an integral part of the Philippine landscape, the coconut tree is also the subject of lore.

Indeed, stretching along the Iloilo coast are defensive towers, but none that equal the size of the Miagao.

In the late 1970s and early 1980s, Thailand and Cambodia sent exchange students to the school to study fish and rice production, and after graduating returned home where they began out-producing and out-exporting the Philippines in these commodities.

In 1984, Miagao Vocational School was converted to Southern Iloilo Polytechnic College (SIPC) to meet the demands of the changing times and for expansion purposes.

Currently, the school offers courses in the fields of electronics and technology, hospitality, and primary and secondary education.
