Southern Liepāja hosts the historic town center Old Liepāja. Large churches of various denominations there tower above old apartment buildings. Baroque Holy Trinity Lutheran Cathedral (1758) is famous for having a 7000 pipe mechanical organ, while Gothic Revival St. Annes (1893) has a great baroque altair (unfortunately, the churches are usually closed).
The area also has multiple pedestrianised streets and old marketplaces. Typical buildings there are two floored wooden residentials and impressive art nouveau edifices. Some of the advertised local sights are the Peter I house (where the Russian czar once stayed) and Latvian music avenue of fame – however these are unlikely to amuse non-locals.
West side of southern Liepāja is framed by a massive beach and an adjoining park. The nearby streets (Dzintaru, Liepu, Vites) are lined by lovely villas of pre-WW1 era German rich (many of them wooden and; unfortunately but atmospherically, a large number seemingly abandoned). One such villa has been transformed into Liepāja museum which houses old things and historical data.
To the south of these historic areas lies a sprawl of single family homes and beyond that a small Soviet district. The city ends with remains of 19th century fortifications that once protected its southern flank.
