The church stands in a scenic valley. In 1589, there were five churches in the Melhus prestegjeld, but Melhus Church was the main one. Two of the five churches were located in Leinstrand and Flå; the remaining two churches were in Hølonda. In 1889, a Royal Decree was issued which ordered that the old Melhus Church be demolished. During this demolition, in 1890, a perfectly preserved hatchet dating from about 1100 was discovered in a wall of the medieval church. This axe was identified as the country's only preserved tool for cutting stone from that period, and it is now located in the Norwegian Museum of Science and Technology. Although the old church was torn down, several architectural elements of the medieval building were saved and incorporated into the new building. Much woodwork from the old church was included in the newer one. The old portal was also reused in the new church. Apparently, a few artifacts from the old church were not moved to the new church, and instead ended up in other places. When Gerhard Schøning visited the old medieval church he noted this: "At the southern side of the entrance to the choir, there is an epitaph that Karen and Anders Helkands have erected to their parents and children". When the medieval church was demolished in 1890, the epitaph was no longer there. Few people knew that the epitaph was hidden on Søndre Melhuus farm. The newer church building has been carefully maintained for over one hundred years; it has had several renovations. In 1999, Medieval runic inscriptions were discovered on the medieval portal. These inscriptions were professionally examined in 2001.

The "Petter Dass" portrait
Melhus Church houses a collection of painted portraits, primarily of clergymen. The most well-known painting is one that has traditionally been considered to be a portrait of Petter Dass, a 17th-century Norwegian poet and hymn writer. The painting was thought to be the only existing portrait of the poet. A few years ago, after some nearby churches were set on fire, there was a debate as to whether the portrait was secure enough. Some historians however believe that the subject of this famous portrait is not Petter Dass at all, but the clergyman Oluf Mentzen Darre. For example, Kåre Hansen is absolutely certain that this portrait has nothing to do with Petter Dass. Subsequently the Petter Dass Museum became involved in the controversy. S. Gustavsen found it strange that the portrait is still shown on the Petter Dass Museum web site, commenting that to consider this painting to be a portrait of Petter Dass is the same as to still "believe that the earth is flat and the sun orbits the earth." The museum itself cannot prove whether the portrait is of Petter Dass or not, and so they feature the debate on their web site.
