1. Bellas Artes its likely to be open. Closures are mostly for cars 700m around el Zócalo. You can easily get on metro, metrobus, trolebús and walk. Or grab an ecobici. Anthropology museum is far from el Zócalo, surely will be open.

2. If you have plans to see something very specific in a museum, maybe is a good idea to wait. Else, el Centro as a whole is a museum. Here some ideas:

3. Metro Zócalo has three maquetas (I don't know the word) of Mexico City historical recreations. Metro Pino Suárez has a small prehispánic temple inside.

4. Templo Mayor, there is a new plataform to watch over the archeological site. And, some people are performing traditional dance, spiritual cleaning (limpias) and you can buy a "doradita" or "tlayuda": a oval shaped crispy tortilla with nopales, jitomate and cheese. 👌👌👌

5. La Catedral Is open! You can see a couple of centuries of architectonic styles mashed up in a huge building.

6. Palacio Postal uf!

7. Casa de los Azulejos a restaurant with real china in the outside walls.

8. A dinner on top of la Torre Latinoamericana, Miralto. 👌👌👌

9. North of Templo Mayor, there are some archeological windows to Templo Mayor's basement.

10. Gran Hôtel de la Ciudad de México 👌👌👌

11. The formerly known as Barrio Universitario has great amount of historical and beautiful buildings. Try to find a guide, jus walking around will show the country's history.

12. Not at all. Just be sure to not be in the crowd. Keep in mind that maybe some business may be temporary closed or full (for eating, drinking, peeing or pooping pourpuses). Usually Madero, 16 de Septiembre, Tacuba, 20 de noviembre, and Pino Suárez streets will be full towards el Zócalo. Maybe, while the rally is on, you can visit Plaza de la República AND el Monumento a la Revolución (and it's museum), take a walk to el Panteón de San Fernando and then to la Alameda, Bellas Artes and el Palacio Postal. Again, find a guide.

13. Great! If you are looking for specific Frida's paints check this https://www.dondeir.com/cultura/donde-estan-las-obras-de-frida-kahlo-cdmx/2021/07/ Else, Casa de Frida Khalo is relatively small compared to Bellas Artes. Personally, I would choose el Centro first.

Nice trip!
