The Casas Colgadas (Hanging Houses), is a complex of houses, of uncertain origin. In the past, houses of this kind were frequent along the eastern border of the ancient city, and they could represent a response to overcrowding and a lack of other building options. We overhear a local guide tell a bunch of US tourists that in the 19th century they were the world's biggest sky scrapers.  In fact, it is known that they date back to the 15th century. 

They have been used as individual homes, council houses, and currently host a restaurant and the Museo de Arte Abstracto.  

The iglesia de San Pedro has a beautiful chapel ceiling, I could look at it for hours.

In contrast, I cannot walk over the Puente de San Pablo quick enough.  It's quite scary crossing the gorge this way, but I want to keep my companion happy.  The bridge was originally built in the 16th century to  connect the old town with the San Pablo convent (now the parador). In fact, the original bridge collapsed, and the current one was built in 1902, of wood and iron.

The origins of the Mangana Tower are unclear, but there is evidence for it's existence in the 16th century.  It was rebuilt in the 20th century following damage in a thunder storm.  It has a clock on one of its walls and a recording of bell chimes can be heard in the old town every quarter of an hour.

I loved Cuenca and feel sad to leave.  
Next, we are on the slow train to Madrid and admire the countryside of the mesita.  We change at Aranjuez by simply crossing the platform.
