General
Characteristics
Compact limestone, fine grain and cream dark colour with noduls in terracota.
About its extraction, in medium and small sizes, is made in the called
Serranía de Loja (Granada), in working fronts of scanty length
quarries, of one only bank.
About its superficial ending, take any suggested type of this kinf of
stones, its use must be adapted to the current rules on limestones what
take shine from the polish.
Representative works made in this material:
Liceo de Mérida (Badajoz)
Edificio Embajada - Puerto Marbella (Málaga)
