Thanks for focusing on the issue! A Visigoth site would be great. Yeah, it seems one of those broad nominations which needs rephrasing. A little like the mining heritage, maybe? :-)

Jasam alerted me to 2 aspiring TWHS in the Canary Islands:

- Historic Center of Las Palmas (by a "Citizen Platform")
- Old Sugar Mills of the Atlantic (serial with Dominican Republic) (seems more serious, will be on the new Spanish T List, "includes the one in Guía de Gran Canaria, together with those in Telde, Agaete and Los Llanos de Aridane, to which are also added four from the Dominican Republic")

Plus some more on the new Spanish T List:
- Geode of Pulpí (Almería),
- the Laboral University of Gijón
- the rock engravings of La Palma

Current sugar mills in Dominican Republic tent list are as follows:

-Ruinas del Ingenio de Engombe
-Ingenio Boca de Nigua
-Duquesa Sugar Mill (demolished after tent list inscription)
-Ingenio Azucarero De Sanate

If they are going to add 4 sites from Dominican Republic, the fourth will be a surprise then. I hope they update other tent sites in Dominican Republic as well while they are updating it for sugar mills.

Perhaps it's a bit soon to be speculating, but - with Frank Gehry's death late last year, how likely is it that plans for a nomination for the Guggenheim Bilbao (+ likely others as a serial site) start getting underway? I was interested to see that a committee member mentioned the possibility when the FLW site was up for inscription (https://forum.worldheritagesite.org/index.php?action=vthread&forum=16&topic=2233&page=19#msg22298), and it seems to me from reading some of the discussion around the Siza nomination in 2025 that no longer being about a living architect would make success more likely.

To be frank it's not obvious to me which of his other designs are distinctly spectacular - they all look rather similar to me (!). Maybe the Dancing House would be an 'easy add' since it's already protected (within the Prague WHS core zone).

A serial site would be likely to include at least one US location, though, so maybe requiring US input and co-operation would be a blocker for the moment.

We were in Northern Spain Last May.
From my Impression Guggenheim and Bodegas Marqués de Riscal could be a standalone joint WHS.

The dancing House is Not very unique, and any way already within Pragues corezone.
