A deep well was constructed in Upper Songculan, Dauis, Bohol in the year 1900 by a Spaniard leader. The locals provided the labor. The well depth is more or less 30 fathoms (55 m; 180 ft) and the diameter is more or less three metres (9.8 ft). Information revealed that the well was constructed through manual digging using bolos, crowbars, pulleys, and rope for digging into the soil stones, which contains limestone rock.
The first bridge between poblacion of Dauis and Mansasa, Tagbilaran was constructed by Spaniards during their reign, possibly in the 18th century. The bridge is still there and in place, used as a connection between the two islands. The other bridge was constructed near the old City Hall of Tagbilaran City, crossing towards Totolan, Dauis. That bridge is known as 'the causeway' and leads as far as Panglao Beach resort about 17 kilometres (11 mi) from Tagbilaran.
The town's 18th-century church, is dedicated to La Señora de la Asuncion or Our Lady of the Assumption. The church is believed to have been built of light materials by the first Spanish missionaries in 1697. Since then, the church has gone through several changes.
The image of the La Señora de la Asuncio is famed to be miraculous. Faithfuls from afar hike the distance from their city to the site to invoke special petitions or mainly to honor the Patroness. In addition, at the foot of the altar of the church is a well also believed to have healing power. The water tastes fresh, despite the well's proximity to the seashore.
The town and all devotees of the La Señora de la Asuncion attend the Patroness' feast day every 15 August. Stories abound of the Patroness' sojourn and blessings. One of the stories tells of a man who found a camiseta (small shirt) in his fishing boat after a lady passenger disembarked. On several occasions, devotees found the Patroness' camiseta full of amorseco. Many believe the Patroness must, on occasions, get down from her pedestal to visit them in their homes and farms. To this day, devotees continue to venerate and pay homage as manifestation of gratitude and appreciation after being healed of their ailments through the camiseta.
Last Sunday of January
Another fiesta is celebrated last Sunday of January, to commemorate a miracle that happened many years back. It is said that many young girls have seen the lady waving her hands as if bidding them to come near.
