The year 1799 was engraved on a tomb in this church so that year was taken as the year of construction.
Stefano Gondola in his 20 October 1647 will leaves instructions for the building of the church of the Lady of Carmen and he asks that a religious church item be made of gold for the church of St. Michael.
The Vručica priest don Juraj Gabrić confirms having received the gold from the state treasury and those are the oldest references found for this church.

That was at first a very small church that was not mentioned in any of the bishop's visits from 1621 to 1805 whereas the little church of St. Anthony is mentioned.
That would mean that St. Michael's was either smaller or not in use.
Even in 1800 it is not mentioned in a separate list while all other churches are named.

In the land registry map from 1836, the church is labeled as church of St. Michael.
It was a small church with probably one wooden altar displaying a group of saints: St Michael with a scale, to the right St. Peter with keys and to the left St. Paul.
Above them was the virgin Mary surrounded by angels and flowers.
This altar probably had the pendant of St. Michael and Peter that is now in the church of St. Anthony.

The main altar was built in 1849 by Domenico Bertapelle a famous altar maker from Vrboska.
The other two altars, the entrance stones and the classical window Rosetta stone came from the church of St. Peter.
Until 1902 the door and window were at the front of the church which was decorated by stone bell-niche with 3 bells.
This niche was damaged by thunder in 1858.
In 1854 a new altar decoration was purchased showing St. Liberan, St. Blaise, and St. Jovinian protector of olives.
This was replaced in 1907 by a statue of St. Liberan which was a gift of Ivan Čibilić, who was living in Alexandria.

The statue of the Lady of Rosary was purchased in 1855 from Italy and a lithography of the statue was made in Verona to be used as the town seal.
The statue was brought to Trpanj on 20 May 1855 and that date was celebrated as a holiday until 1912.
The king Franz Joseph I visited the church on 11 May 1875 while on his tour of Dalmatia.

Prince Joseph II of Liechtenstein who frequently came to Trpanj to hunt for čaglje (a wild dog native of Pelješac resembling a hyena) made a gift of 2 bells in 1888.
Since the niche could not support the large bells, they were taken down in 1897 and hung next to the church.
The town then decided to expand the church and build  new bell tower.
The prince of Liechtenstein contributed 150 fiorns and the town 2000 crowns.
The work started in 1902, and the new roof and sacristy were completed in November 1904 and the new bell tower in 1905.
The church and 5 new bells were consecrated on 28 April 1907 by bishop Marcelic.
The marble statues of St. Peter and Paul were made in 1907 in the Bilinic workshop in Split.
In 1912 began the construction of the staircase leading to the church and in 1916 the space around it was paved.
The old fence wall consisting of benches was replaced with the current stone columns between 1917 and 1918 thanks to father Dinko Suljaga.
The paintings in the church were made by the local painter Frano Ferenca between 1929 and 1930.
