In addition to the cathedral, Torre Tagle Palace and the Iglesia y convento San Francisco, the historic heart of Lima conceals a host of other fine buildings from the colonial era. The charm of this district, a UNESCO World Heritage Site, owes a great deal to the bewildering variety of beautiful wooden balconies that adorn the facades. As you stroll around, look out for those of the archbishop's palace, Casa de Osambela and the Torre Tagle Palace.
