The Reign of Mary, Queen of Scots is coming to an end on The CW. The period drama's upcoming fourth season will be the show's last, TVGuide.com has learned.

The drama series, which stars Adelaide Kane and Megan Follows as the young queen Mary and Catherine de Medici, respectively, is currently filming, which means the show will at least have a proper conclusion as the writers are crafting a series finale. The fourth season premieres Friday, Feb. 10 and will be 16 episodes. That tentatively puts the series finale airing in mid-June, so although this is the end, there's plenty of time for fans to prepare for the end.

Here's What the new CW schedule means for your favorite shows

This marks The CW's second cancellation this season after the long-running The Vampire Diaries, which will sign off in March after eight seasons, and opens up some much-needed space on The CW's crowded schedule. But this news probably shouldn't come as much of a surprise to Reign fans. The show's ratings have been declining — Season 3 moved to Friday nights where it averaged less than a million viewers in adults ages 18-49 and a 0.3 rating — and the fact that it was renewed for a fourth season at all was a bit of a surprise.

Additionally, several original cast members have departed the show recently. Both Toby Regbo (Francis) and Anna Popplewell (Lola) left the series last season when their characters were killed off. Meanwhile, Torrance Coombs, who plays Bash, is no longer a series regular. He departed at the end of the third season and will appear in ABC's midseason series Still Star-Crossed.

Reign returns Friday, Feb. 10 at 9/8c on The CW.
