When the women first see Ravensbruck in The Hiding Place, Corrie uses two similes. What are the two similes?

Corrie Ten Boom's The Hiding Place is a chilling account of the suffering experienced by political prisoners during the Holocaust. In the book, Corrie details her life and the imprisonment that resulted from her family hiding refugees from the Nazis. After the arrest, Corrie is sent to a number of prisons and work camps. Chapter 13 of the book details the experience of Ravensbruck, a female work camp/concentration camp in Germany. Upon arriving at Ravensbruck, Corrie employs the use of two similes:

From the crest of the hill we saw it, like a vast scar on the green German landscape; a city of low grey barracks surrounded by concrete walls on which guard towers rose at intervals. In the very center, a square smokestack emitted a thin gray vapor into the blue sky.
Ravensbruck!
Like a whispered curse the word passed back through the lines. This was the notorious women's extermination came we had heard even in Haarlem.

The similes "like a vast scar on the green German landscape" and "[l]ike a whispered curse" create a sense of fear within the reader. In comparing the concentration camp to a scar, Corrie makes the reader feel as if the very existence of the camp is the remnant of a wound. In this case, the atrocities committed by the Nazis have wounded the country and resulted in a scar that blights the very land on which it stands. Comparing the name of the concentration camp to "a whispered curse" also creates a sense of dread and fear within the reader, as if even saying the name is an immoral act. This, too, reflects the horror of the camp and shows the further degradation that has occurred as a result of its existence.
