Kronborg Castle, meaning "Crown Palace", was built in 1574 and completed in 1585. The funds came from the tolls collected by King Frederick II (1559-1588) on ships passing through the Øresund Strait. The castle was designed and built by a Dutch architect. The palace is built of rocks, and the brown copper roof is majestic and magnificent. It is the most exquisite Renaissance palace in Northern Europe. There is a memorial relief of Shakespeare on the wall of the outer courtyard of the palace. It is said that Shakespeare wrote the immortal tragedy "Hamlet" with Kronborg Castle as the background.
