Memorial complex Petrova niva
The area of "Petrova niva" is located north of the village of Stoilovo (municipality of Malko tarnovo). It is known as place where in 1903 was held a meeting of VMRO (Secret Macedonian-Adrianople Revolutionary Organization) and when a decision for the Preobrazhenie uprising was taken. The rebellion was scheduled to rise together with the Ilinden uprising (in Macedonian region) and aims joining of Eastern Thrace, Aegean Thrace and Strandja to Bulgaria. The uprisings failed but it remained the high point in fights for the National Liberation of the Macedonian and Thracian Bulgarians.
