Fortified gateway

A fortified gateway is an element of a variety of fortified structures, such as a castle or walled town.

[1] Fortified gates or gateways appear in the Bronze Age and reach into the modern times.

Medieval castle gateways of this type usually have additional fortifications in front of them.

A common form is the tower gateway (German: Turmtorburg); a variant is the bastion gateway (German: Halbrundturmtorburg).
