She really wants to go to Europe.

Literal

She [topic-は] very Europe [toward-へ] go-want-show is.

ヨーロッパ entered Japanese from Portuguese (Europa) in the 16th century with Catholic missionaries, then settled in as the standard term — pronunciation closer to the Dutch/Portuguese than to the English. へ marks direction of motion, slightly more formal/written than に for the same role. ~たがる + ている stretches her wanting across an ongoing observable state.
