Kedu Plain

It roughly corresponds to the present-day Magelang and Temanggung Regency of Central Java, Indonesia.

The Progo River runs through the center of this plain, from its source on the slope of Mount Sundoro to the southern coast of Java facing the Indian Ocean.

There is a small hill near Magelang called Mount Tidar that is referred to as the Nail of Java.

[2] According to Javanese legend, the gods placed the nail to prevent the island of Java from sinking into the sea from tremors.

The Kedu Plain hosts a large number of Hindu and Buddhist temples dated, from the 8th to the 9th century.
