Blieskastel (German pronunciation: [ˌbliːsˈkast(ɘ)l]) is a city in the Saarpfalz (Saar-Palatinate) district, in Saarland, Germany which is divided into villages.

The districts of Niederwürzbach, Lautzkirchen and Alschbach are located in the Sankt Ingbert-Kirkeler forest area.

Alphabetically these are Altheim, Aßweiler, Ballweiler, Bierbach an der Blies, Biesingen, Blickweiler, Böckweiler, Breitfurt, Brenschelbach, Mimbach, Niederwürzbach, Pinningen, Webenheim, and Wolfersheim.

Castle and lordship came into possession of the Counts of Salm, then in 1284 of Bishop Burkhard of Metz, who relocated there from Finstingen.

In 1440, the Elector of Trier, Jakob I, turned over half of the county and the "Hungericht" to the knight Friedrich von Loewenstein.

The palace was further expanded and on the Schlossberg there were a number of outstanding palaces and mansions for the court officials of the small court, including the so-called "Schlößchen", attributed to the Zweibrücken building director and architect Christian Ludwig Hautt.

With the French Revolution, the von der Leyen were expelled in 1793, their palace plundered and subsequently destroyed.

From 1920 to 1935 Blieskastel belonged to the Territory of the Saar Basin (Saargebiet), which was put under French administration by a mandate of the League of Nations for 15 years.

Altogether, the historic area of Old Blieskastel comprises 133 individual monuments and a further 65 buildings under ensemble protection.

The church was designed by a Franciscan builder named Minder, the construction was led by the Count's Inspector Peter Reheis.

In the Holy Cross Chapel at the pilgrimage monastery there is, since 1827, a baroque painting of "Our Lady with the Arrows", which was transferred in 1786 from Gräfinthal to Blieskastel.

The landmark of the city is the 4000 year old Gollenstein, which is considered to be the largest menhir in Central Europe at 6.5 metres (21 ft).
