East Germany decided to upgrade the fortifications in the late 1960s to establish a "modern frontier" that would be far more difficult to cross. Barbed-wire fences were replaced with harder-to-climb expanded metal barriers; directional anti-personnel mines and anti-vehicle ditches blocked the movement of people and vehicles; tripwires and electric signals helped guards to detect escapees; all-weather patrol roads enabled rapid access to any point along the border; and wooden guard towers were replaced with prefabricated concrete towers and observation bunkers. 
Children born on or after 1 January 2000 to non-German parents acquire German citizenship at birth if at least one parent has a permanent residence permit (and had this status for at least three years) and the parent was residing in Germany for at least eight years. The children must have lived in Germany for at least eight years or attended school for six years until their 21st birthday. Non-EU- and non-Swiss-citizen parents born and grown up abroad usually cannot have dual citizenship themselves (but exceptions are made for citizens of countries that do not allow the renunciation of citizenship or have too expensive / difficult / humiliating renunciation procedures).
