Every evening at 17:49, a strange sound drifts across Senate Square: five minutes and eighteen seconds of chimes hopping from one Neoclassical facade to the next, like a modern glockenspiel that has learned to walk. It is a small oddity in a square built for grander gestures.

The square takes its name from the Former Imperial Senate, now the Government Palace, one of four matching buildings the German architect Carl Ludvig Engel designed after Russia annexed Finland in 1809. Engel liked the commission so much he moved his whole family to Helsinki and stayed for life, work that still frames the square today alongside the cathedral, the university and the national library.

VoiceMap's self-guided audio tours use Senate Square as the starting point for exploring Helsinki, tracing Engel's Neoclassical vision through the city centre and explaining how a Tsarist administrative seat became the capital's civic heart.
