There is an international airport in the near town of Wroclaw.
The Polish State Railways  has train connections from Wrocław but since 1997 the connection to Świdnica (In fact anything via) has been halted. The regional rail operator Koleje Dolnoslaskie  has train going from Wroclaw Glowny that takes 1-1.5 hours (sometimes require a connection).
From Wroclaw, local minibus departs from a side road outside Wroclaw main bus station with several departures every hour (time table ). The journey takes about 1 hour to reach the bus stop in Swidnica next to the train station.
The Peace Church (Ksciol Pokojowe) is on the UNESCO World Heritage List- dating from the 1600's and built out of unusual materials (wood and hay), it resembles a theatre or opera house more than a church. Covered top to bottom in beautiful, old, folk-art-style paintings, the Peace Church is absolutely worth a visit.
Behind the Peace Church is an old German cemetery which, as of July 2008, was completely overgrown, giving it a creepy atmosphere and making it a great destination for photographers and seekers of the arcane.
Attend the summer Bach Festival in July. Concerts are held in the Church of Peace and other venues in the town. For further details go to www.bach-cantatas.com and follow the links through 'schedule of concerts' and 'Bach festivals'.
