reference of its

What is "its" referring to? Is it referring to "Thomas Schutte’s Hotel for Birds"?

Context:

Arguably, then, the supposed ‘readability’ of Alison Lapper Pregnant is entirely apposite for a piece of public sculpture that will be experienced by most people – whether visitors or London residents – in passing. Its ‘instantaneousness’ as a resonant counterpoint to Nelson and company is, therefore, exactly its strength and, moreover, not necessarily the only level at which one may wish to engage with it. But it gives momentary pause for thought perhaps to the busy pedestrian around the themes I have touched on above, in the same way that Thomas Schutte’s Hotel for Birds, which followed it, patently attempted to say something about the ‘tourists-and-pigeons syndrome’ associated with the square. Its specific critique of the ‘place of statues’ in London’s performance of the story of itself as a city could also be said to be the lingering trace within the space of the public imagination – or perhaps it was the public unconscious – that prompted the time-based Trafalgar Square mob freeze: a theatre of mortal statues.
