How to buy it from Spain
In euros it trades on Xetra as SXR8 and on Borsa Italiana as CSSPX; on Euronext Amsterdam and the LSE as CSPX (in USD on the LSE).
As an ETF, it is outside the Spanish tax-free switching regime: selling it to buy something else realises the gain. If that matters to you, the index-fund alternatives are listed on the index page.
