West of the Albertinum is the Brühlsche Terrasse , a spectacular promenade that’s been called the ‘Balcony of Europe’, with a pavement nearly 15m above the southern embankment of the Elbe. In summer it’s a must for strolling, with expansive views of the river and the opposite bank. Beneath the promenade is the Renaissance brick bastion known as the Kasematten , which has a museum showing how the fortress was used.
