Describe the characteristics of the St Pancras Station in Statue of John Betjeman's Background.

As reviled as its creator for much of the 20th century, in the 21st, St Pancras was renovated in a multi-million pound, and much admired, restoration. Its significance is recognised, Simon Bradley describing it as, "this greatest of High Victorian secular buildings" and its Historic England listing suggesting that it may be "Britain's most impressive station", with only the Great Eastern Railway terminus at Liverpool Street station being posited as its rival as, "the largest and handsomest railway-station in England".
