What were Susie Wong and her partner looking at?

Susie Wong and “亞肥” took us to Macau to look at a building on Avenida de Almeida Ribeiro (亞美打利庇盧大馬路). What was it?

It was the Institute of Civic and Municipal Affairs (民政總署大樓). Facing opposite to it, crossing the road, was the famous Senado Square (議事亭前地).

Susie Wong and her partner were sitting on a narrow bench looking at a plaque inside this building.

I would like to show you the plaque and photo of the actual building for comparison. How many percent do you think the picture on the plaque look like the real one?
