Declan Devine has made his first new signings as Derry City boss with Peter Cherrie, Ciaran Coll and Ally Gilchrist moving to the Brandywell.
Winger Jamie McDonagh also signed a new contract as Devine gets to work in his second spell as manager.
Cherrie, 35, was back up to Mark McNulty at Cork City last year and is among the most experienced goalkeepers in the league.
Long-serving Derry number one Ger Doherty is expected to leave, with the club saying it is expected Cherrie will battle it out with Nathan Gartside for the starting role.
Coll joins from Finn Harps where he was an integral part of the side that won promotion in 2018. He has spent a decade at the Ballybofey outfit.
Gilchrist was with Shamrock Rovers last year, where he made 13 appearances for the Hoops.
McDonagh was a bright spot in a difficult season for Derry last year after moving from Sligo Rovers. The Northern Ireland Under-21 international has renewed his contract in what is a big boost for Devine.
