The border lock of the Augustów Canal between Poland and Belarus. A beautiful lock with a lifting bridge and tall pillars. Unfortunately, it can currently only be admired from the Polish side.

Mikaszówka is more than just a lock. The Church of St. Mary Magdalene and the adjacent park commemorating the Augustów Roundup are also worth visiting.

Kudrynki is the last lock before the border with Belarus. It's a small lock with a wooden bridge and manually operated wooden gates. Currently closed due to a breakdown, but it's always worth seeing this structure, built by Polish military engineers during the partition period.

In July 1945, Red Army units, with the help of the Polish Army and officers and collaborators of the Security Office, carried out a large-scale pacification action in the Augustów Forest and its surroundings, referred to as the Augustów Roundup. On the Soviet side, units of the 50th Army of the 3rd Belorussian Front, the Internal Troops of the NKVD and officers of the military counterintelligence "SMERSH" participated in the operation. Officers of the Public Security Office, the Citizens' Militia and local informants supported the Soviets' actions as guides and translators, and also assisted in interrogations. Soviet units searched the forests and villages, arresting those suspected of contacts with Polish independence partisans. We do not know the exact date of the beginning or end of the operation - it is most often placed between July 12 and 28. In total, several thousand people were detained, some of them imprisoned and subjected to brutal interrogation.
