Think of something that the usual damage simply never reached. Time passed, and the things that normally change a place or a person — building work, crowds, money, attention — either stayed away or arrived and made no mark. So the word praises by naming an absence: nothing was added, nothing was taken, it is still what it was. There is often a quiet sense of luck in it, and sometimes of something worth protecting.
From the word’s history
Wiktionary gives unspoiled as un- plus spoiled. The whole meaning sits in that negative prefix: it names what did not happen, and English spoil covers both damaging a place and indulging a person, which is why the one word reaches both.
Wiktionary 記載 unspoiled 由 un-（沒有）加上 spoiled 組成。整個意思就住在那個否定的字首裡：它講的是「沒有發生的事」。而英文的 spoil 同時可以是「弄壞一個地方」和「寵壞一個人」，所以同一個字才伸得到兩邊。
