Brennerský / Praniarsky tajch

River-basin: Hron

Brennerský water reservoir – this was built before 1500 in the village Grintál /the Green Valley) above Banská Hodruša. It is one of the oldest water reservoirs in the Štiavnické Hills; it was made higher several times and was used as a source of propellant water for extraction devices in the mining Plant of Althandel. After building up of Dolný Hodrušský water reservoir this one lost its original purpose and so it has been left derelict.
