Inconspicuous and somewhat hidden, you'll discover a drinking fountain here, or at least that's what our inquiries revealed. It was once used to provide drinking water. Even today, people fetch baptismal water or Easter water here. An old custom on Easter night or on Easter morning before sunrise, during which water is drawn from a spring, stream, or river.
It's also said that in much earlier times, the water was even warm. However, this isn't entirely verifiable. It's certainly a great fountain with a place to sit.
