As a port city founded in the 13th century, Liverpool has spanned from the Plantagenet Dynasty, the Lancaster Dynasty, the Yorkist Dynasty, the Tudor Dynasty, the Stuart Dynasty, to today's Hanoverian Dynasty.
The relatively peaceful environment has also cultivated a diversity in the local architectural styles, whether it's the clearly defined, spire-filled Gothic architecture, the half-timbered Tudor style known for its striped appearance, or the Georgian architecture that has been popular for a century, blending Baroque curved forms with Rococo decorative elements—in Liverpool, you can see them all.
As for Castle Street, where Liverpool City Hall is located, that's where the Tudor style is concentrated.
