Kahraman said in news conference at Dolmabahce Palace in Istanbul the museum would be built so that "people's efforts to prevent the coup against democracy on July 15 will be never forgotten and democracy will be kept alive".
He also confirmed damaged sections of the Turkish parliament had been repaired.
Turkey’s parliament was bombed by coup plotters during the Fetullah Terrorist Organization (FETO)’s coup attempt.
The offices of the prime minister and some areas with traces of bomb damage will be preserved.
Turkey's government has said the defeated coup, which left over 240 people martyred and nearly 2,200 injured, was organized by followers of Fetullah Gulen, who has lived in self-imposed exile in the U.S. state of Pennsylvania since 1999, and his FETO network.
Gulen is also accused of a long-running campaign to overthrow the state through the infiltration of Turkish institutions, particularly the military, police and judiciary, forming what is commonly known as "the parallel state".
