The town of Siedlce is situated in the Masovian Voivodship in the east of Poland near the Belarusian border and about 90 kilometres from Warsaw, the country's capital. Siedlce has more than 70,000 inhabitants and can easily be reached by train from Warsaw. SOS Children's Village Siedlce was built on a four hectares site on the town's outskirts and is surrounded by forests. The children attend the local schools and kindergartens, which greatly supports their integration into the local community. The official opening ceremony was held on 10 June 2000 in the presence of numerous friends, donors and other honorary guests.

SOS Children's Village Siedlce consists of twelve family houses, a house for the village director, flats for the SOS aunts (who support the SOS mothers and take care of the children when the mothers are on leave), a community building, an administration and service area, a workshop and a room for medical treatment. Additionally, a sports field and a playground were created. Up to 78 children find a new home in the cosy and welcoming family houses.

An SOS Youth Facility for up to 16 youngsters was established in 2006. An extension of the existing SOS Children’s Village by two additional family houses is scheduled to start in 2007.
