The case I knew from my hometown was that the Church (as in country organization) payed one third. The congregation hat to pay one third as well and the secular municipality also had to pay one third.
In Munich the "Allianz Arena" (named after a big insurance company) for the FC Bayern was also substantially supported by the tax payer. More than one third of the estimated costs were planned to be payed by the government. As they cannot subsidize directly that was mostly the cost of the infrastructure like streets, power, water and so on. The richest socker club in Germany argued that the tax payer has to finance it, as the city would profit from the visitors.
If I remember correctly, BMW got 150 million subsidiaries (from the EU and Germany) for building a new production site near Leipzig as it was seen as helping the development of the former GDR states after the fall of the Berlin Wall.
Seems like a regular thing at any scale for any organization/company with enough lobbying power and influence.
