Gua Maria Kerep, Catholic pilgrimage cave in Ambarawa, Indonesia.

Gua Maria Kerep is a Catholic pilgrimage site in Kerep village, Ambarawa, Central Java, built around a cave with statues of Mary. It lies in the Bruderan garden, about 500 metres from Ambarawa bus terminal, and includes a Via Crucis, an open-air prayer area, a church and gardens, with views of Mount Telomoyo, Mount Merbabu and Lake Rawa Pening.

Gua Maria Kerep was founded in 1953 on land in the Kerep hamlet of Ambarawa, Central Java, and began as a natural cave turned into a Catholic prayer site. Local pupils of Saint Joseph and Santa Maria schools carried river stones from the Sungai Panjang together with children of the Bruderan asylum and nuns. On 15 August 1954 the shrine was inaugurated and blessed with holy water from Lourdes by the Archbishop of Semarang.

The cave serves as a gathering place where Catholic communities come together for prayer and religious ceremonies throughout the year. It holds deep meaning for pilgrims who view it as a center of spiritual practice.

The shrine lies on Jalan Tentara Pelajar in Panjang, about 500 m from Ambarawa bus terminal, set back from the main road. Pilgrims reach the Via Crucis, open-air prayer area, church and garden on foot within the grounds. The site is managed by the Parish of Saint Joseph in Ambarawa.

The grotto was inaugurated and blessed on 15 August 1954 by the Archbishop of Semarang with holy water brought from Lourdes. Local pupils of Saint Joseph and Santa Maria schools, together with children of the Bruderan asylum and nuns, carried river stones from the Sungai Panjang to build it.
