The key attraction of Yogyakarta is 'Kraton' (the Sultan's Palace). The Sultan's palace is the centre of Yogya's traditional life and despite the advance of modernity; it still emanates the spirit of refinement, which has been the hallmark of Yogya's art for centuries. This vast complex of decaying buildings was built in the 18th century, and is actually a walled city within the city with luxurious pavilions and in which the current Sultan still resides. Yogyakarta is also the only major city, which still has traditional 'Becak' (rickshaw-style) transport.
