Closed door for enemy

Ukrainians are always hospitable, but they will close the door to their enemies.  And will be kicked them out of the yard.
This door is in the  private museum in Chernihiv region. Museum keeps interesting historical and archeological materials of this region.  
But in February of the 22nd year they had to be securely hidden.  Because the enemy was passing by.  And only a miracle saved it: the museum is located on both sides of the main road.  Today, most of the exhibits are still hidden.
