The bullring which was built in 19th century has hosted its last corrida in 1975 being later restored and redesigned into a hotel which has preserved the feel and the beauty of its original structure .

Any bull that behaves " strangely " during the corrida at this month 's feria de san isidro in madrid will be tested for drugs after the fight is over .
