This puzzle is part 13 of Gladys' journey across the globe. Each part can be solved independently. Nevertheless, if you are new to the series, feel free to start at the beginning: Introducing Gladys.
Dear Puzzling,
Today I visited a certain tall building. Not recommended if you're afraid of heights! In the evening I'm planning to watch a light show. This marks the half-way point of my trip, so plenty of places left to visit. Take care!
Wish you were here!
Love, Gladys.
Gladys will return in "A game of cricket".
