Lisbon - more historic buildings

We arrived in Lisbon by train from Coimbra tuesday
Lisbon, like Porto has a huge number of old buildings dating mainly from the fifteenth to eighteenth century.
Yesterday we went to Belem and saw a huge Monastery which now houses two museums in addition to the church and the cloisters.
Lisbon has quite an extensive tram network. Like Porto it has a lot of hills which the trams seemto climb but for the very steep streets there are furniculars - all dating back to the nineteenth century though some of the trams are more modern.
There are lots of museums and a port right next to the city over which looms the remains of the ancient castle and several cathederals. One cathederal was partially destroyed in the 1753 earthquake which devasted the city. The city (largely destroyed) was rebuild on a grid and this part forms the centre of the city which is surrounded by broad avenues and parks, as well as a few crowded slums, which are quite picturesque in the way the compact tenements climb the steep streets exhibiting the washing of the inhabitants on frames slung from windows over the narrow alleys.

The pictures show the Cloisters in the Monastry that was built to give thanks for the discovery by Vasco da Gama of a sea route ( via the cape of Good Hope) to India. Taxes on this trade paid part of the cost - and were the reason for Portugal's subsequent prosperity , (aided also by otber colonial trade particularly Brasil).
The next picture is the attached Cathederal, and the last picture in the waterfront square, Praca do Comercio, which is a huge open space between the old town centre and the river Tagus.
