'Pretty Little Liars' stars share photos from the final day on set

LOS ANGELES, Oct. 27 (UPI) -- The cast of the hit Freeform drama Pretty Little Liars shared photos from the last day on the show's set as filming wrapped on the seventh and final season.

The show centers around a group of friends from fictional Rosewood, Pa., who are locked in an ongoing battle with the ever-mysterious "A," a villain determined to destroy their lives.

The show is loosely based on a book series by Sara Shepard and premiered in 2010. It was announced in August that the show will end after its seventh season.

Filming wrapped on Wednesday, and the cast shared behind-the-scenes photos from the final day.

"The day has come to say goodbye to my second home, a character that helped shaped me and so many people who mean the world to me. Bittersweet feelings today, but so proud of what we've done," Lucy Hale, who plays Aria Montgomery, shared on Instagram along with a photo of the main cast laying in the grass with their heads together.

Ashley Benson, who plays Hanna Marin, shared another photo of the cast saying, "Seven years later the day has come to say goodbye."

The series, which also stars Troian Bellisario, Shay Mitchell, Sasha Pieterse, Keegan Allen, Ian Harding, and Tyler Blackburn, returns to Freeform in April for its final season.
