Pekalongan is the batik city of Java's north coast. The title is not just a slogan: batik is woven into the local economy, education, markets and neighbourhood life, enough for UNESCO to list Pekalongan as a Creative City of Crafts and Folk Arts.
The best introduction is the Pekalongan Batik Museum, which explains motifs and techniques from across Indonesia. After that, the city becomes more interesting on foot or by short rides between workshops, showrooms and market streets. Kauman and Pesindon are the classic batik kampung areas, while Pasar Grosir Setono is the practical place to see how much cloth moves through the city.
Pekalongan is a working textile town rather than a polished heritage city. That is part of the appeal. Stop here if you are travelling the north-coast rail line between Jakarta, Cirebon and Semarang and want a focused look at one of Indonesia's living craft economies.
