Art, culture and plant identification

I wrote a really long post yesterday about our visit to two of the art galleries in Madrid, but something went wrong and most of it disappeared.
Today we've been doing more exploring. We visited the Egyptian temple and the Banksy museum - so a day of non-Spanish culture in Spain. The only photo I took on my phone today was this shot of a Spanish plane tree, which I took for identification purposes on the PlantNet app - so not artistic in the least.
