Jagna is located on the southern coast of Bohol. It is one of the commercial trading centers of the province with daily market and port operations. Of interest to visitors is the town church built during the Spanish era, with its ceiling frescoes and baroque architecture. A waterfall and a spring reservoir can be found on the highlands, accessible by road travel north. A marine sanctuary zone has been set up by the local government just off the shore. A double reef is protected inside the sanctuary zone and marked off by buoys to restrict access from fishers.
On January 24, 1744 an Italian Jesuit curate in charge of the town parish was killed by a native insurgent known as Francisco Dagohoy. This event signaled the beginning of the Dagohoy Rebellion – the longest uprising in Philippine history.
The Lonoy Massacre in 1901 was a bloody American surprise attack launched on Filipino insurgents – the latter being led by Captain Gregorio Caseñas[a] – that killed over 400 in the Philippine-American War. It was fought in the mountain village of Lonoy, north of the town proper.
A major earthquake devastated the town in 1992. The local residents were evacuated to the nearby hills for a few days, as local authorities warned of a possible tsunami that might hit the coastal area. Fortunately, no such event happened. One major damage wrought by the earthquake was on the church bell tower. Since then, the damage has been completely repaired.
Jagna has a new market; the last one burned down in 1998 and a temporary market was set up in the grass field across the church. The new market is in operation – built on the site of the previous one that burned down. A recreational plaza is recently in construction on the grass field that was once the temporary market area.
Like Tagbilaran, Jagna is a port town. Ferries travel daily to and from other islands. Routes to Mindanao are available via Cagayan de Oro and Butuan. The island of Camiguin is visible from Jagna and a daily ferry operates from Jagna to the port of Balbagon.
The town celebrates St. Michael's festival on September 29. Highlights are cultural activities such as parades and street dancing. The month of May is also of interest, especially to returning Jagna-born Filipinos from across the islands and abroad. Celebrations of barangay fiestas – with food, drinks, and local night disco – one after the other, occur almost everyday during that month.
