Eija-Riitta Berliner-Mauer, 54, whose surname means Berlin Wall in German, wed the concrete structure in 1979 after being diagnosed with a condition called Objectum-Sexuality.

Mrs Berliner-Mauer, whose fetish is said to have its roots in childhood, claimed she fell in love with the structure when she first saw it on television when she was seven.

She began collecting "his" pictures and saving up for visits. On her sixth trip in 1979 they tied the knot before a handful of guests.

While she remains a virgin with humans, she insists she has a full, loving relationship with the wall.

Mrs Berliner-Mauer, who lives in Liden, northern Sweden, said: "I find long, slim things with horizontal lines very sexy.

"The Great Wall of China's attractive, but he’s too thick – my husband is sexier."

While the rest of mankind rejoiced when the Wall, erected by the Soviets in 1961 to halt an exodus from East to West Berlin, was largely torn down in 1989, its "wife" was horrified.

She's never been back and now keeps models depicting "his" former glory.

She said: “What they did was awful. They mutilated my husband."

She is said to have shifted her affections to a nearby garden fence.

Objectum-Sexual or objectophilia is feelings of love, attraction, arousal, and commitment for a particular object.

The mere thought of a relationship with an actual human being seems ludicrous.
