The harbour, enlarged in 1823 to accommodate vessels of up to 500 tonnes deadweight, has a pier dating back to the 15th century which has also been renovated. Queen Victoria disembarked from the royal yacht at St Michael's Mount in 1846, and a brass inlay of her footstep can be seen at the top of the landing stage. King Edward VII's footstep is also visible near the bowling green. In 1967 the Queen Mother entered the harbour in a pinnace from the royal yacht Britannia.
