For the Geo Quiz, we are looking for a town in Andalusia, a region of southern Spain.
Semana Santa or Holy Week celebrations are under way in that town.
It is located in Huelva province, not far from Portugal and the Atlantic coast.
The town is famous for its spectacular caves and underground lakes known as the Gruta de las Maravillas.
Aracena is the answer to the Geo Quiz.
Producer Christopher Burrell sent us an audio snapshot of the Holy Week festivities from Aracena.
