This uses a hidden word technique combined with reversal. A hidden word means the answer is concealed within consecutive letters of other words in the clue, and reversal means those letters are read backwards.
Look for the answer hidden within consecutive letters in the middle of 'Worcester'. The word 'centrally' tells you to focus on the center part, and 'elevated' indicates you need to reverse/read backwards the letters you find.
Answer: CROWN | The answer is hidden in the center of 'Worcester' - take the middle letters N WORC, then reverse them ('elevated') to get CROWN.
