Pier Head
From Tardis Wiki, the free Doctor Who reference
Pier Head was tourist attraction in Liverpool.
When he was caught by Sontarans aboard an Imperial Sontaran Time Carrier, Dan Lewis feigned ignorance and replied "All right, lads. I was just looking for the Pier Head?". He claimed to be a lost tourist. (TV: War of the Sontarans)
Behind the scenes
Although not made explicit in War of the Sontarans, Pier Head is part of Liverpool's waterfont which was seen in both Welcome to the TARDIS... and The Halloween Apocalypse. The Museum of Liverpool is located there.
