Swiss Tax on Selling foreign real estate owned by a foreign company??

Does anybody know if there is any Swiss tax to pay for a Swiss tax resident if he sells:

• Foreign company that owns foreign real estate and he realizes capital gain on sale of the company? Is capital gain tax payable in Switzerland or in the country where the company is domiciled? i.e. real estate is owned via a company (e.g. Spanish company owns Spanish real estate) There is no capital gains tax in Switzerland on listed equities but is there any on privately owned foreign companies?

• If the foreign company who owns foreign real estate sells the real estate and then pays out all money to the shareholder as dididends and then the company is closed. Will there be a dividend tax to pay in Switzerland or in Spain or both?

What is the most tax beneficial way to sell this real estate? The sole purpose of the company is to hold real estate so the company can be closed if real estate is sold.
