Riga, Tallinn and Helsinki. Despite their differences in style, the fascinating architecture of these three cities is a constant throughout our tour. In Riga, marvel at the grand Gothic and classical art nouveau houses. In wonderful Tallinn, amble magnificent medieval streets. In the Finnish capital, modernist buildings sit pretty alongside traditional wooden structures. We’ll tick off the big-name highlights in each country, but you’ll also capture an intimate, local perspective of the culture and history.
