Lviv city is quite old one, more than 750 years old. It was founded as a city of Galicia principality, by king Daniel. As his son was Lev, he named the city after him. For a long time (from 14th to almost end of 18th century) city belonged to Poland - Lithuania Commonwealth, later - to Austria till 1918. Later it was a part of Poland again, Soviet Union and finally Ukraine, from 1991. So it is possible to see how much changes city got, no wonder it looks like Central Europe city as Krakow, Vienna, or Prague.
Lviv is about 30 kilometers from Zhovkva.

After you have explored Zhovkva, you might consider visiting the St. Nicolas Monastery nearby. this serene and extremely quite place, located just 12 km from Zhovkv, can be a great ending for this one-day trip.
Krekhiv Monastery is believed to be found by two monks, Ioil and Silvester, who settled in the cave not far from the current monastery. the current monastery complex, which consist of St. Nicolas church, the belfry, cells and defense walls and towers have been built, dates to 18 century. the monastery has been built as a fortress to protect people during Turks and Tatars raids.
the place is in a great condition, restored and well-taken care of. besides the monastery, you can take a hiking trip to see the cave in the woods, around 3 km off the monastery; follow the sign - Pechery - that points out uphill; the other sign leads to the miracle spring)
the place has been also known as a place for religious pilgrimage. It can be very crowded during St. Nicolas celebrations, May 20-22.
