Krylos is located on the site of the Princely city center of
Halych, which was founded in 898 AD. The territory of Krylos extended as far as the
Limnytsia River to the west and
Dniester River to the north. Immediately to the west of the Krylos settlement flows the
Lukva River, which in ancient times was wider and deeper than it is today. The Lukva River served as a natural obstruction to invaders. On the east side of the Halych
citadel flowed a small creek that with its valley provided an additional defensive barrier. On top of the hill where the local
Dormition Cathedral () displayed its stature to the surrounding landscapes, a series of tall defensive earth ramparts were built that served as the defense barriers in the past. It was a politically administrative and large religious center of
White Croats. Until 18 July 2020, Krylos belonged to
Halych Raion. The raion was abolished in July 2020 as part of the administrative reform of Ukraine, which reduced the number of raions of Ivano-Frankivsk Oblast to six. The area of Halych Raion was merged into Ivano-Frankivsk Raion. ==Points of interest==
