The village elders claimed that the trunk's size was so great that it required six adults to hold hands to reach around it.

[6] Archaeologists were shocked to find significant artefacts that demonstrated the region was occupied as early as before the 12th century during working on the Mengkubau Dam in 1997.

According to a Berita Muzium article from the January–April 1998 issue, archaeologists found pieces of broken Chinese Vases from the Song dynasty.

[7] The government, working through the Brunei and Muara District Department, began building a short road that led to Kampong Sungai Besar in the 1960s.

The road connecting Kampong Mentiri and Jalan Muara was also constructed in 1968, and since then the village's population has grown, reaching 1,121 individuals and 186 homes at that time.

These homes had split bamboo walls, bulian wood stilts, and thatched nipah palm roofs.

Local customers are currently served by a department store and a global fast food restaurant.

[7] The loss of the original residents' primary livelihood, rice farming, comes with the village's opening to the outside world.

[7] Along with being involved in the community, Majlis Perundingan Kampung (MPK) Mentiri also works to improve the income and standard of living for the villagers through economic ventures like the sale of flower pots, agricultural goods, weaving, carpentry, fisheries, and monthly sales stall activities.

The public is invited to stop by the monthly sales booth since it will be beneficial to do so given the variety of goods that are offered there from 8 am to 8 pm.

Those from the villages who were traveling to Brunei Town walked up to Bukit Sibanging and boarded a bus along Jalan Muara.

With the presence of several shopping centers and complexes, retail stores, workshops, a car company workshop, and a gas station, a safe and orderly road system has a positive impact on Kampong Mentiri's surrounding areas in terms of economic and industrial development.

As part of Brunei's 24th National Day Celebration and with the involvement of over 150 individuals, MPK organized the Bukit Mentiri Climbing Challenge in 2008.
