fortressed
Enclosed by ramparts
Fortressed means enclosed or protected as if by a fortress—surrounded by strong defenses or barriers.
The word usually appears as a past participle functioning as an adjective: a fortressed city, fortressed behind layers of security.
It suggests deliberate isolation or protection, often with connotations of impregnability: She remained fortressed in her office, refusing all visitors.
